[mythtv-users] Mencoder XviD encoding Sanity Check

[Christopher Meredith]

Couple things off the top of my head:
* I would suspect the main problem is your trying to scale the output
to 352x320, which is not a 4:3 aspect ratio. Try 512x384 instead.
* You can used -aspect 16:9 or -aspect 4:3 to avoid those ugly decimals.
* I also normally see the filter chain specified very close to the
beginning (i.e. mencoder infile.mpg -vf ...)
* Why are you using the -idx option while transcoding?
