How to copy a TV programme DVD RW?

[Peter McL]

In my computer, I've got a DVD player - Hitachi DVD-Rom GD-5000, and a DVD recorder - Sony DVD RW DW-U14A. I copied TV episodes from video tape to a DVD+RW via my Phillips DVD recorder. Now I've decided to keep them permanently, I'd like to copy the DVD+RW to a DVD+R, but when I try to use Clone DVD, I get this error message.. "D:/VIDEO_TS/VIDEO_TS.IFO:21 unable to open file". Is this because Clone DVD will only copy DVDs with pre-recorded films on them, and not ones you create yourself from TV programmes? Any ideas how I can copy my own DVDs? I tried Media Player, but it won't recognise that there's a disk in my DVD player.

Thanks for any help.
