    Hi

    Just watching my freshly delivered copy of MU and the True HD audio keeps dropping out for a second from about half way through the film

    Anyone else having this or do i need to start checking my equipment ?

    I have the same issue with my copy, the only difference with mine is that the sound drops at different stages whenever i've played. Originally it was from the very start but the last time it started from about 5 minutes in.

    Swapping to the Dolby 2.0 and letting my amp matrix a surround effect cures the problem, but obviously it's not a great solution.

    I've emailed Disney to see if they're aware of this as it appears to be a mastering error

    A quick google of this shows those in the states are reporting the same issue

    Dont bitstream on your Blu-ray player go into your audio settings and select pcm and that should sort the problem out.It just means that the Blu-ray player is decoding the audio and not the amp,and you wont see the Dolby true HD logo on your amps display.Ive had this with a few Disney titles(brave,monsters inc 3d).

    Thanks. I've not had this on other Disney blus to be honest

    If the disc has a HD audio track it should work correctly. We shouldn't have to administer a work around so that the audio doesn't drop out

    If it's a mastering issue, Disney need to put up a replacement scheme ASAP

    Yes i know what you mean,and it can be frustrating i also had a problem with Total recall(2011).It only seems to be Dolby true hd sountracks as ive never had an issue with Dts Hd master audio.Im using a sony bdps470 Blu-ray player.

    Its not technically a mastering issue, last year Dolby changed the way they encode their TrueHD 7.1 tracks which has caused issues on certain player/amps which can only be sorted by the manufacturers fixing the bug and releasing an update but this doesn't seem to have happened for most.

    For the record this is the 4th Pixar title effected by dropouts but switching your player to output PCM instead of bitstream seems to fix it for most, not ideal I know but I can guarantee that is what Disney will end up suggesting anyway as its what Sony came out with when people were experiencing the dropouts on Total Recall.

    Sure it would be nice if every disc worked in every player first time but we know this just isnt the case, pretty much all BDs start up with a warning saying this disc has been manufactured to the newest specifications and might not work on your player so we have to rely on the manufactures to keep their players up to date and sadly this just doesn't happen especially for older lines which they tend to stop supporting at all once their newer fancier unit is out.

    Thank you everyone for your postings - assumed it was my Oppo playing up with audio dropouts so played on my Panasonic player instead which was OK. Quite relieved to know my player is fine and that there is a fix for the problem. Never had any problem with any Disney blu ray's before and have virtually got them all.

    It seems to only effect titles that have TrueHD audio (Pixar titles / Disney use DTS-HD for their classic range) and use seamless branching, this is the reply someone received from Oppo...

    I'm using an LG BDP-420.

    Knowing LG's customer support, it would be a waste of typing to ask them about a f/w update for this issue

    Same issue on my Oppo BDP-83 as well. Brave and the US release of Finding Nemo were problematic too.

    Switching to PCM solves it. If only they had just stuck with DTS-HD MA!

    PCM downmixes it thought right? So doesn't really solve it.

    Not sure if it down mixes it (could be wrong, like), but absolutely it doesn't solve it and is my point entirely

    A workaround shouldn't be the answer

    With your player set to bitstream it will send the audio to your amp and let it decode it, with the player set to PCM it will decode it instead so the amp doesn't need to, this will for most fix the lip-sync/drop outs issue and the quality shouldn't be effected, it is still lossless audio.

    Yes, I have experienced the audio drop outs tonight on both 3D and 2D blu ray discs. Very annoying, and they did not occur at the same points throughout the first 30 minutes I tolerated it before switching off.

    Straight back to Tesco tomorrow, house full of disappointed kids.

    Did you try the workaround mentioned above?

    Well no as I have 8 kids from the street in for a movie night. I've just put another film on for the time being, but I will check later tonight. Although I agree with what has already been written, I don't want to or should have to check for workarounds to play a movie.

    I've checked my other Disney blues which have True HD audio tracks and they play with no issue.

    On my set up, the problem is solely with MU

    I never had any issues with Brave or Finding Nemo either but suffered 3 dropouts while watching Monsters University which caused lip-sync issues however I have seen reports of others having dropouts ever 30 seconds which indicates its a player incompatibility issue which isn't anything new, a lot of people had trouble playing the Alien Anthology, Star Wars Saga, Avatar and numerous other titles but as time went on the manufacturers fixed these issues with firmware updates and now those problem discs play just like any other.

    I am not trying to defend Disney but problem discs which don't actually have anything wrong with them have happened many times before and you can bet this won't be the last time.

    Yes I went off to read about Linear PCM vs Bitstream and if you're using HDMI for audio then you are alright. The player will decode the track to PCM before sending to your receiver maintaining the multi channel lossless sound. It's only if you're using optical which can only transmit up to 2 channels of PCM data where it is downmixed.

    Still I think these types of problems should not exist and the manufacturers should fix and reissue the discs. Playing movies should not need to rely on constant firmware upgrades, especially since some players don't get any updates at all!

    I have just finished watching my 3d copy and thought there was an issue with my set up. I had 3 drops and then went out of synch. I had to choose dvd then back to blu ray inputs and it corrected it. No point sending it back now then I will try the workaround next time. Thanks all

    Thanks for the tip about letting the blu ray player doing the decoding. I'm letting it play through in the background and 30 minutes in I've not heard any drop-outs. Hopefully I won't need to take it back to Tesco today.

    If you are only using optical then lossless audio is impossible anyway as it will just playback the core DTS or DD track if set to bitstream and neither of these suffer from dropouts anyway.

    Having everything work first time would be my preference too but DVD had similar issues (had to take my Samsung 709 to Dixons to have a chip fitted so it could play The Matrix) so I don't expect things to change with BD, they will keep trying to push the format and this will cause trouble for some players, my LG doesn't like the way Sony have started mastering their releases and results in the screen going black quite regularly but the same disc works just fine on my PC and PS3.

    Watched with the kids earlier, and the entire film played back perfectly, letting the player do the decoding.

    Thanks again for the tip guys!

    No problem here. Played faultless. Will list my settings/player/amp if it helps?

    Is this just on 2D, or on 3D too?

    Both as they have the same 7.1 TrueHD track.

    Thanks Indy.

    As an aside, it's been mentioned on the Disney Movie Rewards thread in the Bargains section, but for wider exposure they initially listed the MU blu and 3D blu as being higher points values than was intended (3D was 450, not sure about 2D). If you email DMR they'll add the extra points to your account :)

    Does the US version have the same problem too?
