Got this DVD burner from Frys few months ago burning was fine perfect for backup, now I can't make a perfect copy, playback the middle and/or especially the end of movies where the copy movies keep skipping/stalling, etc.. I have tried several different medias, burning @ vary speed 1x-4x all with something wrong.

I'm trying to pinpoint whether is the burner or the PC..? Anybody have an ideas or similar problem with their Polaroid burner?

Thanks in advance!

You did not really say exactly what model number you have, but if you look over to the left at the DVD Writers list, and search for Polaroid, you won't find too many good reviews.

If I'm not mistaken this is Polaroid only first DVD Writer (internal) for PC, besides I already checked before post dvdrhelp.com doesn't have it listed.
