There's no telling what the DAR is with PAL 720x576 dvd's.
pyTivo fails miserably with this res unless the version of ffmpeg
being used returns PAR/DAR.  Hence the reason I added the
dar1 = 4:3 or 16:9 fix a while back.  Latest Windows ffmpeg versions
return PAR/DAR, but don't know about versions compiled on other OS's.
And then I suppose it's possible that the DAR could be other than 4:3
or 16:9.  In which case, pytivo will assume 4:3 again.  Still
considering modifying pytivo to check for dar2>1.35 but have
not run across a file yet that did not report dar1 = 4:3 or 16:9.
