@Christian, 
Thanks so much!  I have NO (very rare) additional skips now in OE, A4-3400 HDMI
to Sony LCD.  On 1080ix29.97 h264.  I have been trying to fix this for a long
time.  I have some really hard to play panning vids that used to skip a lot,
and it is now none.  1080px23.976 h.264 = perfect.  @Peter thanks for posting
the patch.  PQ is amazing!  No judders at all.  

I forgot to mention the 210 PLL limit works great too.  Thanks for that also.

@Jereon.   I hope that this fixes your issues.  This bug report has made a huge
difference for my systems.

Garrett
