Hi all, I hope someone can help me.. I have a Sony 930 amp and a sony S335 DVD player (15 months old and modded for multiregion) connected via a coaxial cable. Tosh 36ZP18 is also connected to amp via phono leads. The amp can 'sense' the digital format being sent to it eg DD, DTS, pro logic, and displays this briefly whenever it changes (only for a few seconds - it then resorts to displaying the input source ie DVD). So for example I start the DVD with Gladiator in. The menus are in DD 2.0 format so this gets displayed on the amp before showing "DVD". When you start the Gladiator commentary, which is pro logic, the amp shows "Pro Logic" and after a few seconds resorts back to show the source (in this case it just shows "DVD"). Recently though the amp keeps getting a 'new format being sent' signal from the player and thus keeps switching to the sound format being broadcast. So after a period of time (which is random - a few seconds, minutes) the amp thinks the DVD player has just sent a signal to change the sound format so it shows up on the display as just being received. Now this wouldn't be too much of a problem except for the fact that when the amp senses a new format being sent to it, it stops the sound for a fraction of a second. Then when the amp recognises the format it starts sending out the sound in that format. So while watching the gladator commentary the fomat being sent changes to "Pro Logic". But after a bit the amp senses that this format is being sent again and thus stops the sound for a fraction of second while it changes to the new format (which of course is the same as that which it is already in !). Now the amp doesn't do any of this with the TV (via phono connection). And the DVD player doesn't do it when connected to the TV via scart and the TV sound is used. So I've narrowed it down to three things : 1) The dvd player is faulty in respect to the digital connection 2) The digitial cable is faulty 3) The amp's digitial input is faulty. I don't have a spare coaxial/optical cable to test the DVD player out. I'm sorry if I've gone a bit - it's a hard one to explain. This has only recently started happening (just out of the warrenty period !) and is really bugging me - I can't watch a film with the sound being interrupted every now and then. Any one out there who has experienced this or something similar - maybe with a different amp or player ?? I have double checked the coax connection and it is firmly in place so I've no idea what to do. Any help appreciated. Cheers.
