[mythtv-users] Frontend crashes during FF/REW

[DaveD]

I posted something a while back about FF/REW not working as well 
starting with V0.29, but I'm now thinking it may have started because I 
upgraded my hardware and version at the same time and maybe it's because 
of the hardware change and Intel onboard vs Nvidia.

Since V0.31, my frontend crashes if I try too many things during FF/REW 
(like reversing direction).  Today I got around to taking a look at the 
frontend output during FF (after a FE crash) and, although this doesn't 
show a crash, it shows a LOT of output during FF operation.  The sample, 
below, repeats over and over during FF (which is not very smooth or 
responsive to control input).  I'm thinking the performance problem is 
due to the FE continuously attempting to "va_openDriver()" and 
re-creating "VAAPI 1.6 display for VAAPI DRM".

Is this normal?  Should I be installing something that's missing?  
Should I try different playback profiles or change some settings?  Might 
this be an indication of what's causing the poor FF performance and/or 
crashes?
