help with dvd -r

[pricey79]

i am prettty new at this but here is my problem. I bought a lite-on dvd+-RW external burner and everything was working fine. I was using memorex dvd +r discs. A friend gave me a load of tdk dvd-r discs to burn. Now when i use dvd shrink with the dvd-r's it will go through the encoding process and then will stop as soon as it starts burning. The error message says something to the effect of "illegal disc." i thought maybe i just got some bad discs but i tried a pack of memorex dvd-r's too and had the same result. Has this problem happened to anyone else, or does someone know a way to fix it? any help would be much appreciated.

It still could be bad media (we need to try more than just two batches, to know for certain).

But -- note this. A friend had a new Lite-on burner (about 2 months ago). He saw illegal discs on every DVD-R he tried, including Ritek and Taiyo Yuden (widely praised as the best). He knew that Lite-Ons were better with DVD+rs, but still most people managed to get the better DVD-R discs to burn fine.

His symptoms... He could rip fine; everytime. But, when he tried to burn, though, the process began, (barely) and then seemed to go for about two to four minutes, but the software seemed locked on1% or 2%. It did not increase. Finally, after two to four minutes of this, it would spit out his disc and give him an error that said "illegal disc." This was all using Nero as his burning program. DVDDecrypter was tried as a burner with similar results. It too said "illegal disc" as it spit out the disc. He did manage to get ONE DVD+RW to successfully burn, but none of the DVD-Rs he tried (five brands) worked.

Then, he came across someone on the Internet who had the same Lite-on burner, and who had previously experienced very similar errors -- illegal disc, when he got to the burning process. This guy suggested he needed to uninstall Roxio, since some of those drivers could cause conflicts with his Lite-on.

My friend tried it -- he uninstalled his Roxio product completely, and voila! He has burned successfully now more than 40 discs with no failures, after his first 22 attempts were all "illegal disc" coasters.

If you do not have Roxio, then obviously that is to be ignored.

Anyone else?
