[QUOTE="sjeffrey, post: 513986, member: 81884"] I think you are right about being the only capture card that supports TOSLink as far as an analog capture card. We could look at code from internal cards and see what they do. I'm not sure this is the right way to go though. One question is, if the stream audio is only stereo would the same graph be built then a stream with AC3/6 channels? Unless stereo means AC3/2channels, which would then be the same graph. To further prove my theory about the PVR hitting the end of stream on the timeshift buffer, we could make a patch to log timestamps on each packet and see what's going on when it stutters. The main reason why I'm convinced this is the case is because playback of recordings or pausing for a few seconds fixes the issue. I also noticed that it's NOT just channel changes. When you hit commercials and switch from 5.1 to 2 then you'll see the blue led flicker and MP starts to stutter. If anyone knows how it behaves in Sage or MythTV (is it even supported?) then it would be interesting to know if they have the same issues. If they do, then it would point us to the actual HW or drivers. [/QUOTE]
