As we say in London "This is doing my 'ed in"
I have had numerous tries, taking on board your advice, with the same results.
Well not quite the same as at various times when using the RE disc I got messages
"this disc is not supported by your drive"
"this disc is not blank" and when trying to delete it "this disc is blank" !
Anyway, I managed to get a playable film on both the RE and another -R disc, but both had a slight 'freeze' near the start putting the rest out of sync (but OK on VWave)
So, I think I am going to give it a rest until the New Year - not going to be at home much anyway - and then start from scratch again.
Thanks both for your help - just one unanswered question to CD - how do you get to the Options menu that you sent ?
Finally Seasons greetings to you
