Creating libs/libmyth/mythconfig.h and libs/libmyth/mythconfig.mak

WARNING: When using --enable-proc-opt you must include the

libs/libmyth/mythconfig.h is unchanged

Running nvidia driver 7676

I've attached gdb.txt and log.txt; log.txt is -v playback. I performed some 10 minute jumps and then some 30 seconds skip forwards until I got close to the end, then let it "run out". This is reproduceable for any MPEG-2 content captured from my PVR cards.

Signs are pointing to OpenGL; within mythfrontend I changed from Standard XvMC to Standard; OpenGL vsync is still enabled. Still got a crash when we ran off the end of the recording.

With OpenGL turned off and XvMC turned back on, using Bob deinterlace I don't get a segfault when the program ends; get returned to the Watch Recordings screen.

rkulagow, there is a bug in recent nvidia drivers that makes XvMC not work with OpenGL vsync, nvidia is aware of the problem and has promised a fix in a future release. I'm running version 66.29, but there are reports on the mythtv-user list that one of the 7x.xx versions works as well. AFAIK none of the 8x.xx versions work.
