Advertisements For the past year, I've been using my S3 with the Dolby Digital to PCM setting enabled and just the stereo speakers on my TV. I decided it was time to enjoy 5.1 surround with my HD recordings, so I hooked up a receiver and changed the TiVo setting to Dolby Digital. I figured that the HD channels would be Dolby Digital, but the SD channels would just be regular stereo. But the receiver says that EVERYTHING coming from the S3 is Dolby Digital (with the exception of the menus). I can't imagine that ALL of my channels are encoded with 5.1 surround channels, so is the TiVo doing its own encoding to 5.1? Is there a way to have it just pass the native audio so that HD channels get sent as 5.1 and SD channels get sent as stereo? Basically, I only want to lose the TiVo sound effects if I'm truly getting 5.1.
