DTS troubleshooting, please help me

[Test005]

Hi
I have some DTS problems with my home cinema.
Some films just don't work with DTS. The sound from the speakers is sort of a chopped up "bo-bo-bo"relflecting any sound made in the movie.
Totally impossible to hear anything else than this stuttered "bobobobo". I've tried to boot all equipment, re-insert movie, doublechecked all settings and connections.

Resident Evil & Black hawk down=Has this problem (works ok in DD)
Gladiator & Blade2=Works good in DTS

I have a no good, no name DVD player (Scott) could this be the first component to troubleshoot/switch. (But DVD is not decoding, Amp decodes, right?)
Amp is Maranz SR-4200.

Anyone have any ideas or similar problems?

Hi

First thing to check would be the dvd player. Can you not borrow a mates to see if that works with your Marantz?

If it works ok then it´s your player that´s the problem. If his plays up as well then it´s the Marantz that has a fault.

Not being rude but I assume the dvd discs are legit?

Legit? sure, 100% original, bought for big money in the local DVD shop.
Could there be some probs with the discs aswell? I mean, is it common that people buy faulty discs or a certain series has a malfunctioning sound track?

Hmm, maybe it's time to throw out that old DVD player anyway. Bad picture with lots of bleeding thru when it's showing black/darkness.
The Maranz is expensive like !"%¤ So I guess I go for a Sony, any recommendations?

You can get faulty discs but I´d eliminate either the player or the amp first. Actually you could check the discs on someones dvd player first all just to make sure they´re ok.

Don´t know much about the Sony range to be honest but Marantz stuff is usually very good.

Hang on. I´ve just remembered something. The Marantz 4200 had problems with DTS tracks, sound popping etc. Have a look at this thread.

Sounds like you need to get it modified by Marantz.

Thanks for all the feedback Jase. I checked the link you posted but I don't seem to have similar problems.
They mention pause, play=crackle in one backspeaker and I've read about this phenomena before.
Also I can't remedy the situation by switching source or mode and then back to DTS.

I can't reproduce that problem, because when I use the DTS track on one of my "problem discs" There is no way to get any acceptable sound from the speakers.
I have pom-pom-pom from all 5, pausing/playing/changing chapter/ffwd/rwd...whatever, still the same.

I wish it would be consecuent with all my DTS movies, but it seem to be 50/50 chance.

Need to investigate and possibly return the unit if it's faulty....
Feels bad because I have been lurking in this AV shop for a long time before I picked up the 4200 and now after just a few weeks I'll be back complaining. **** I don't like this! I'll be the poor salesmans worst nightmare!

Best to investigate, like you say, but if the amp is faulty then the dealer should replace it or get it sorted out. I´d try and get my hands on another dvd player first of all, as that will help you eliminate what the problem is.
