DVD skipss in the middle

i use nero vision express 3 to encode and burn avi to dvd

but each time i burn a cd and play it on my dvd in around the middle of the movie it starts skipping and than freezes and restarts to the begining of the movie

is it because i was doing stuff while it was burning ?

how can i fix that???

thanks

 

Could be because your multi-tasking. Could be crap media. What discs are you using?

 

Could also be burning too fast. Not overburning are you?

 

i use maxell 8x cds, not sure if its good cds
