[QUOTE="sjeffrey, post: 739791, member: 81884"] I whish I knew... Do you get drift on recordings too? At first when I had 2 HD-PVRs I would only use them to record because LiveTV wasn't working "enough" to be usable. Now since I only have 1 client, the main tv, I set the priority so that the Colossus is my LiveTV card and the HD-PVR is more often my recorder card. The unscientific way that I see what happens for it to stutter is that when you watch live TV you are following then end of the stream (the timeshift file). When a broadcast switches over to commercial then no audio/black screen could cause the HD-PVR to stop send data in the buffer momentarily. Since you are playing back the live stream then you kind of go over the end of the stream which has no data and the decoders don't know what to do, until finally you get more packets from the PVR. This causes stutter and/or audio drift. With DD on this is even more noticable because most broadcasters switch to stereo during commercial breaks and back to DD after the commercials. The PVR seems to handshake everytime the stream changes and again this is enough to break the continuity of the data stream read by the decoders. Again, this is mostly speculations as I don't really know the internal workings of timeshift files and codecs. I've been meaning to try this codec but I think one of the downsides is you lose pass-through audio correct? I guess since we can't really use DD now we wouldn't loosing a whole lot... Anyone tried MP audio rendered yet? [/QUOTE]
