Comment (by J.Pilk@…):

 I've been testing transcoding from DVB-T2 (UK) to near pal-dvd format.
 Using ffmpeg I see artefacts - mostly small random rectangles; using
 mythffmpeg from a week-old build of 0.26-fixes, they aren't there.
 ATrpms and related builds, el6 i686.

 Bad version:  built on Mar 20 2012 04:56:34 with gcc 4.4.6 20110731 (Red
 Hat 4.4.6-3)[[BR]]


 Good version: (myth)ffmpeg version 0.10.2.git Copyright...
   built on Dec 16 2012 16:32:40 with gcc 4.4.6 20120305 (Red Hat 4.4.6-4)

 mythffmpeg -threads 2 -v verbose -i
 "/home/john/Mythrecs/1102_20121207205600.mpg" -target pal-dvd -b:v 6000k
 -s 720x576 -acodec mp2 -b:a 256k -ac 2 -aspect 16:9
 "/mnt/MythOnRoot/Mytharch_work/work/1/newfile2.mpg"

 Of course it's much easier to get something like this by recording the SD
 version...
