Glad it worked for you. The quality will not be as good as if your TV
had the right setting.

I spent a considerable amount of time helping a guy on mythbuntu
forums who swore black and blue that his TV didn't have this setting,
only to be told in the end that he found an undocumented "Just Scan"
settings in the aspect ratio settings.

TV manufacturers do seem to hide these settings though. There is some
info at http://pixelmapping.wikispaces.com/ but the site doesn't seem
to have been updated for a while.
