Dvd Rom and DVD RW with buffer problems



In the past you guys have helped me , so I hope u can help me this time too.
well, my dvd rom, jlms xj hd 166s, and my dvd rw sohw-1953s… take ages to rip and burn discs , both drives are in different ide channels…one thing to consider is the buffer bar wich jumps like carzy, and most of the times is 0% , Ive tried to reinstall ide channels with no luck…
Ill accept ideas…
