New DVD R probs... again!

Hi, I'm new to the forums. Greta site too.

I recently bought an MSI DVD burner for my pc.
Then after about 1 month it started going funny.
When i play DVDs from the drive the are all "skippy", cracks/pops in the sound, and jerky frames.

I was playing with media player, (which used to work fine). Tried other software, same prob, so i returned it.

They sent me http://www.msicomputer.com/product/p_spec.asp?model=DR8P&class=osd

It worked fine, but now its started with the same problem!

Please help as the supplyer had no idea what was wrong with the first one!

Thanks alot

 

Should i just get a differnet brand player?
Im scared the same thing mite happen?

 

I am trying to play store bought/hired, brand new dvds.

Burning is ok, its playback the problem.
Cheers

 

I use Media player, (which used to work fine), and Power DVD 5. Both have the same skipping problem that has just occured from nowhere!
