Complete newbie here, but need some help.

I bought a Samsung R128 DVD recorder just before Chrimble and have been trying to watch downloaded .avi movies on it. Now some are fine, but others are very choppy or blocky when there is any motion on the screen.

It doesn't do it with all films, but the majority. I use to Nero to burn them onto DVD and I am burning them at only 4x.

Any ideas?

Cheers
