DVD Writer won't play DVDs properly

Hello,


I've done a bit of research and some people have claimed DVD Writers has issues playing actual DVD movies. Is this true?
I have a HP DVD Writer 640c that I've rarely used since I purchased it. It does have lightscribe capabilities and such, but it also plays my DVDs.

Now, I recently just purchased the brand mew Twister two-disc Special Edition DVD movie to add to my collection of DVD movies.

Now, my dvds play just fine in my DVD player, and my xbox 360.

However, when I play them on my PC in my DVD writer drive, it plays the movie fine for awhile, but a bit into any DVD movie I play, it seems to just freeze the movie and lock up.

I haven't bothered to try an actual plain old DVD-Rom drive, and I'm not sure if that would stop the freezing.

I'm mostly looking for any suggestions or possible solutions that could stop it. I can try a DVD-Rom, but before I do, I was wanting to hear from experts on the matter so they can clarify if the DVD-Writer is what's causing it itself, and to see if what I read is actually true.

Would appreciate any response. If you need more information, it's below:
