[mythtv-users] Widescreen DVD rip playing letterboxed

[Ian Evans]

All of my DVD mkv's have played without letterboxing, but today I had
one that had letterboxing on all four sides.

Checked the makemkv forums and they said that happened when the source
DVD wasn't anamorphic widescreen. I realize I can zoom, but that
changes the WAF. Is the proper way to handle this going to
Setup->Video->Playback->Zoom->Full? Or does that mess other stuff up
as well?
