[mythtv-users] another mythencode.pl error

[Rob Snow]

Oops, looks like thats a bug (vpass1/2).  I'll get a patch to fix it as soon 
as we get the next patch via CVS.  Robert was away this week and was going 
to apply the patch this weekend.

vhq/v4mv: Actually, I'm not 100% certain either way.  From reading the 
mplayer/mencoder lists it appears you should include them in the first pass 
in some questing/replies and not in others.  I don't have a definative 
answer, but my intuition tells me (possibly wrongly :) that you want the 
statistics from a pass that matches what you are going to be encoding with.
