[mythtv-users] Switched to MythBuntu 9.1, Standard def TV stretch

[Naoyuki Tai]

Hello,

I clean installed MythBuntu 9.1 AMD64. It's up and limping as I am still 
working on setups.
I've been using MythTV since 2003, and have done a few clean installations.
For last two, I used MythBuntu and been successful.
FYI, the mysql sits on a separate FreeBSD machine and the DB schemas all 
updated fine.

Anyhow, the playback of HD is fine, but SD playback is stretched on a 
720p LCD TV.
The SD shows are taped using Happauge's PCI analog capture using MPEG2 
codec at resolution 640x480 or 720x480.

Previous installation was MythBuntu 8.x, and HD played full-screen, and 
SD played as 4:3 without stretch.

How can I set it to not stretch the SD playback?
I went through the setup many many times and could not figure out.

Thanks!
