Yes, true.... I'm not using HD.

However, I would think that the capture file of 16:9 footage would be 
bigger than 4:3 if the frame size (in pixles) is larger, correct?

I'm still trying to close off a few 4:3 projects on my PBook so I don't 
have the room to download any 16:9 footage yet to do my own 
experimentation.

Has anyone burned a 16:9 DVD project yet? Did you notice any difference in 
the length of footage you could have on the DVD to maintain highest 
quality.

Cheers,

Coj

I replied to the original message.
There was no mention of HDV in the original poster's message.
