Sorry to delay my reply; I had a partial PC breakdown whereby my writer drives had yellow flags posted in device manager. I had a recent Acronis backup which has put it all back in order.
Yes, I did try burning the .avi file straight to DVD as a data file but I now see that was the wrong approach. I downloaded DVD Flick and opened an .AVI file from YouTube, and DF converted this (taking some time to do it) into a file with the extension .dfproj, but that is a mere 21kb in size whereas the avi file is 17,056kb.
When I click on the dfproj file DF reopens showing the file as the original .avi file, so what happens next?
Also I cannot see any BURN button in DF so what is the program for?
I should add that I have Nero7 installed but NeroVision doesn't seem to be available, althogh I can burn data CDs and DVDs with Nero Express. This problem might relate to my old PC and its meagre Duron 850 processor which might be inadequate for making DVD disks.
