I want to play a DVD formatted movie in an in car DVD player.

1) can I use CD-R's as the media for a DVD formatted movie?
2) What format (MPG / AVI) do I need to use to add the clip to ULEAD?

It'll be only playing downloaded clips / music vids etc(!) - so I don't need to rip from DVD.

My source files are in MPG or AVI.

Can anyone answer the above and give any advice?
Thanks
