[MPlayer-users] Upscaling

[Tony Houghton]

I've got a DVD which is supposed to be widescreen, but it's really 4:3
with letterboxing. I would like to try to convert it to proper 16:9 by
upscaling, which could probably give a better appearance than "zoom" on
my TV. I've heard that some DVD players have a facility to upscale
ordinary DVDs for HDTV and that they do a very good job, so I wondered
whether mencoder could do as good a job on a smaller scale. The trouble
is there are lots of options for the scale filter and not much
documentation for them, so can anyone give me any tips on how to get the
best quality possible? Eg are any of the alternatives for -sws better
than the default bicubic? Speed of conversion isn't really an issue.
