Hello
I have started to experience problems while burning dvd-r's

when writing a media, 9 out of 10 times, i see a problem with very bad pixilation at the end of the dvd-r, i have burned a lot of Verbatim datalife Plus, with no problems, around 50 discs. But then i started to see the pixilation, so i switch media, tried Ritek, Princo, and Imitation, all have the same problems. When i write on a dvd-rw (Maxell and Verbatim), i have no problems.

I tried to write dvd-r at 1x speed instead of 2x speed, but i still see the problems.

I have tried , Primo DVD 2.0, DVDDecrypter. 3.1.5.0 and 3.1.6.0.
I'm running WinXP.
I have tried playing them on different players, both standalone and PC.

What could it be ? Lack of resources while writing

Any ideas are very welcome.
Thanks
