Burn at 1x or 2x??

[Serpent]

Thanks for the helpful replies, appreciate it,

I have a 1.6Ghz processor and 512MB DDR, even then no multi-tasking?

Anyway, I think this was a firmware issue or the fact that i had the burner on DMA. I reset it to PIO, had the same other program running in the background and i burnt at 1x without any problems.

Ok, since I am using TDK, I can do it at 2x?

Also, where is the "Burn-Proof" option in Primo Dvd?
