Hi to all, new here, hope you can help.
System is Athlon 1 gig
256 ram
4 gig main drive
40 gig second drive
Master cd is Optorite DD0401
secondary is pioneer dvd rom
running windows 2k fully updated
Clone dvd
any dvd
i have enabled DMA on all drives, and this has speeded me up by half, the problem is when cloning a dvd the max i can get it to rip the dvd of 1.5 hours is 48 mins. is there something else i could be doing? many thanx in anticipation.
