This is the problem guaranteed -- other information that gets transmitted
there includes widescreen signalling for European TVs, I see this
occasionally on some channels.

Nuvexport can be used *after* recording to do this. It asks whether you want
to 'crop broadcast overscan'.

VLC does have an option to do this -- I use it all the time to make DVDs
with black bars (cinemascope) fill the screen.

It's in the Preferences (or Options or whatever on Windows) under Video:
Filters: crop. There is a text box for Crop geometry in pixels, fill this
in.

An example is "540x576+90+0" which was written for a 16:9 PAL DVD to make it
4:3. It says take the 540x576 pixel region starting 90 pixels from the left
and 0 pixels from the top.

This is set *globally* so you'll need to turn it off for other files you
view in VLC.

You'll need to know the dimensions of your image (part of the Recording
Profile in MythTV). Say its 480x480, in the box you could put
"460x460+10+10" to shave 10 pixels off each side. Experiment to get the
right dimensions.

Now choose Video: Filters in the options and make sure Crop video filter is
checked otherwise it won't get activated, press Save and try your recordings
again.

Hope this helps.
