Please feel free to move this if it is in the wrong place! First post here!

If I may I would like to ask a question that you will all find easy but I have no idea of the answer:

I own a Sharp DV-L80 and a Panasonic DVD-LS5 DVD players and am about to receive my new Liteon LVw-5045 DVD HDD recorder.

Question: Can I produce a DVD (of a TV prog or similar) that will play on either of my portable players and if so what media do I need and what format should I use?

Many thanks, in advance
