[mythtv-users] UPDATED: pdatranscode

[Jeff volckaert]

Here's my updated pdatranscode script.  I added David Cain's chmod
command so the files can be deleted later via a share.  I also am
using mencoder's lavc mpeg4 now.  This seems to give me the best video
and no sync issues.  The file size is about 140M for an hour long show
minus commercials.
