I am wanting to make a DVD-R back up of a widescreen moive.

When I load the TMPG DVD Template I get the following on the Video tab:

Size is 720x480
Aspect Ratio 4:3 ?

This does not seem correct. My video that I wish to encode with DVD2AVI is 16:9. Shoud I change the aspect ratio to 16:9

I will be watching on a 4:3 TV, but one day I how to get a widescreen TV.

I want the back-up to play correctly on any type of TV. Any ideas?
