It's not at all difficult.  All three of those have some form of GUI 
available.  Just add one of the bad files into the source list in the 
GUI, and hit run.  All it's going to do is take those raw codec streams 
and stuff them into a different container type.  Think of it like 
extracting files from a ZIP archive and putting them in a tarball.  Your 
recordings start as an MPEG TS container, and the lossless transcoder 
outputs an MPEG PS container.  I'm curious as to whether the new bits of 
video are actually damaged, or if something strange is going on with the 
container that is giving MythTV troubles.

All but that first machine listed have nVidia graphics, potentially 
using VDPAU.  I just want to confirm you are seeing this with MythTV's 
software decoder, and not a hardware decoder.  I just skimmed through 
several recordings I've transcoded in the last few weeks and haven't 
noticed any such issues.
