Bought a Matshita SR-8587 some weeks ago, at first I could rip at 6X - 8X any DVD, now sudenly the ripping speed droped for 1.6X - 1.7X maximum .

I did not made any alterations to the pc harware configuration, and don't think any to the drivers also.

I have a PIV 1.5 512DDR the DRU-500 in secundary IDE as master and the Matshita in secundary IDE as slave (the same configuration that when did rip at 8X). Window XP Prof. Edition

In the control Panel I can not change the Matshita to go DMA (DRU-500 is "Ultra DMA mode 2") the Matshita say "DMA if possible" but below does not change from "PIO Mode"

Also have S.M.A.R.T. mode disable ( should I ? )

Can anyone help me please ?.. thanks
