[QUOTE="mm1352000, post: 753480, member: 82144"] Hi GoldenEye Yes, I notice you've been following closely. And *thank you* for your patience. I puzzled over your earlier logs for several hours earlier in the week without being able to find anything particularly wrong and I meant to give you a response. I've looked again at the logs you just posted, and once again I can't see anything wrong. My suspicion is that many of the issues that you're seeing are related to the switching between AAC and AC3 audio. Although TV Server and MediaPortal handle things as best as they can, a lot of the ability to do the audio switching well and smoothly will actually depend on the codecs that you use. As I type this I'm wondering particularly about what happens if you pick an AC3 channel first. You've shown examples of AAC->AAC and AAC->AC3 transitions, but I'm missing the other two transitions - AC3->AC3 and AAC->AC3. What happens with those scenarios? The Microsoft codecs are really convenient because they come pre-installed, but actually they're not always the best and they're not always going to work. In particular with AC3: Source: [url=http://msdn.microsoft.com/en-us/library/dd390676%28v=vs.85%29.aspx]Microsoft MPEG-1/DD/AAC Audio Decoder (Windows)[/url] To me that means that the Microsoft audio codec can't be used for decoding AC3 outside of Microsoft software. Having said that, I don't use Windows 7 at all so I'm going to have to take Microsoft's word for it. Even if it does actually work in MP, I suggest you try FFDShow (@WileE: that's what you're using isn't it?) or AC3Filter (which is what I use - works brilliantly for my live TV, but keep in mind that I don't have a Colossus or HDPVR to test with...). So just to reiterate again: from my perspective really all I can suggest is to try different codecs. Audio codecs in particular.

The sorts of problems that are starting to crop up seem to be more to do with configuration, epg and codecs.
