We're talking about slightly different things.  There is no 0.8 branch 
in the upstream source for the Ubuntu ffmpeg package (they use the 
libav.org fork), so you must be sourcing the ffmpeg.org repo, which is 
also the source of the PPA build.  The short version:  An initial patch 
that addressed the "dud pixels at bottom of HD video" problem was 
committed last November, before the Great FFmpeg Schism.  The PPA ffmpeg 
build carries that patch.  The initial patch was tweaked subsequently in 
the libav.org fork, and that tweak was picked up by ffmpeg.org and 
eventually incorporated in both their 0.7 and 0.8 branches.  There has 
been a more recent tweak in the ffmpeg.org code, but that is only 
available in HEAD.

The upshot for Ubuntu 11.10 users is that you can take your pick of 
ffmpeg implementations.  I've tested the PPA build, the Ubuntu build, 
and a DIY build of 0.8.5 from ffmpeg, and they all appear to handle HD 
video appropriately.  FWIW, I also checked the 0.7.5 version from 
ffmpeg.org supplied with Fedora 15, and it works as well.  If you're on 
an earlier version of Ubuntu, I still recommend you use the PPA build or 
a recent DIY.  Neill says the PPA build didn't work on 11.04, so more 
data points needed to nail that down.  Ideally, we will be able to 
dispense with custom ffmpeg builds in subsequent Ubuntu releases.
