[QUOTE="sjeffrey, post: 422375, member: 81884"] Ok so I'm trying to solve the mystery of my sound stuttering mostly when the channel is Dolby Digital. I was playing with the source code yesterday trying to figure out how things work. I'm starting to understand why most of you are not having issues. As I understand most of you are using analog 2 ch. audio instead of optical AC3. What I noticed last night is if I change from a station that broadcast only in 2 channels to another station with 2 channels audio the "bling light" on the HD-PVR stays on. When I change to or from a station broadcasting in Dolby Digital then the "bling light" shuts off for 3 seconds and turns back on. It seems to me that the HD-PVR is kind of rebuilding it's graph when using AC3 and DD which screws up the timeshifting for a few seconds. The other thing I noticed is that when we are changing channels the timeshift only pauses and then resumes. I know my Bell PVR used to start a new timeshift file after every channel change. I'm not sure which behaviour is the "correct" one. What I was trying to do is to get the timeshift to stop before tuning to a new channel and then start a new timeshift after the tuning. This would allow the HD-PVR to redetect the correct AC3 format(?) and the timeshift file to be clean. I still haven't figured how to do this successfully yet. One thing I have experimented with was to add delays in the code to force TVServer to wait a few seconds after the channel change before looking for audio/video stream. For those who looked at the code before, all I did was change the 1 second delay in the OnNotify to 6 seconds. This worked for the most part but not all the time, sometimes after a few seconds/minutes it would start to stutter again but this could be do to the timeshift file changing. If any of you have some insight or ideas on what could be done that would be great. Am I correct to assume that none of us are successfully using AC3/DD with not stuttering? [/QUOTE]
