I had a similar problem recenty. Mine was due to using an interlaced modeline. The frontend complained when its started playback with the following error: Video sync method can't support double framerate (refresh rate too low for bob deint) So it reverts to onefield (or perhaps no) deinterlacing. The problem is, when you resume from a pause it erroneously attempts to enable bob deinterlacing (without the check that prevented it from being used before) and displays fields at the frame rate instead of twice the frame rate and then quickly realises that the video and audio are getting out of sync and drops frames causing video stuttering. Run your frontend using -v playback and see if you are getting the same error. If you are, bob is not being used anyway, so you might as well disable it. I guess someone who knows about this code should fix it so it checks whether bob is viable when resuming from a pause (or reverting to 1.0x speed after timestretching). Here's the thread where I discussed my problem: http://www.gossamer-threads.com/lists/mythtv/dev/173960 Greg Frost _______________________________________________ mythtv-dev mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-dev
