Hi, On 0.3.5i (2xPVR-350), while watching LiveTV the picture sometimes freezes for a second or two. During such a freeze it looks like the current and previous buffer contents are being switched at V-sync intervals (very annoying flashing). Usually it continues playing after 1-2 secs, but I've also experienced a complete hang. When it continues after such a glitch, audio is out of sync.
I don't have a recording with such glitches, I think it only occurs on LiveTV... Also, when pausing, the 'paused' OSD comes up, the picture stops for one or two frames, then continues for a second or so, then it really stops. forward/reverse skipping also behave in a similar manner. This did not happen in 0.3.5f. Thanks, Stanley. > Is this just using cat?
