I cant copy my own backup dvds with nero or prassi in disk copy mode anymore although both programs will burn the files to a dvd if I 1st copy them to my hard drive. Nero says not enough space on the blank media and nothing Ive tried will make it try to write to the dvd. Ive tried smaller films that are not a full dvd , different brands of blank , on the fly writing and none of it worked. Prassi starts to copy but after about 660 meg it stops saying its finnished and everything is ok. Ive updated both to the latest versions I think , 126.96.36.199 and pxengine 390 and I use a pioneer 104. I dont often need to copy my copies , just when the kids scratch them , it was probably christmas when I last copied any but everything worked fine then. Its not such a problem either when i can just copy the files to my hd 1st and use prassi or nero anyway. Ive seen other people posting similar problems with nero but I haven't seen how to fix it yet so I just wondered if anyone else has seen either of these problems and can suggest anything that might help because I really dont want to format and reinstall windows if I can possibly avoid it.
