    MythTV is just taking whatever the HDPVR wants to send it. You
can take a look at your recordings files directly and see what sort 
of aspect ratio they are supposed to be in. You can play them with
any other video player. They're just MPEG2 containers.

    mediainfo will give you a nicely formated easy to read summary 
of what's in your recording files.
