All of the prebuffering pause tickets seem to involve either DVB or PVR-350 tv-out, however I am still seeing frequent issues with my PVR-250. I left LiveTV on last night to see how it would do and when I woke up it was still working. Great, however, when I checked the logs it contained a nearly endless stream of prebuffering pause messages for the previous shows. Shows either played fine or didn't play at all. For example, I got prebuffering pauses from 3 to 3:30, then it appears to have played fine until 5am, then continuous prebuffering pauses until 7am (it was a 2 hr long show), then it was fine again. There were also mpeg2 errors, however they don't always correlate to prebuffer pauses. Here are some snippets from the logs:

(repeats until 07:00 when it the next program comes on) I was able to rewind to before 07:00 and it played fine, however. In the mythbackend log, the only thing I noticed was a few of these lines: Preview Error: Previewer file '/var/mythtv/tv/1043_20051213040000.mpg' is not valid. They occurred at 1:30, 3:30, 4:00 and 7:00. Only one correspond to a file that mythfrontend had prebuffer pauses with. I would greatly appreciate any help with this. Should I create a ticket or get backtraces?
