Acer CD-R 16x10x40..somthins wrong..

[Tequila]

Ok i have a P3 1GHz 328MB mem a lof of hd space and the latest versions from all cdr software(clonecd, easycd, nero etc..) but it seems that there is a problem...My Acer 16x10x40 is malfunctioning or somethin cause when i try to copy cds most of the times it doesnt copy them very correctly like sometimes it gives me error that it cannot read from specified device(btw i have another cdrom a Toshiba 40x XM-6702B)...and especially when i try to c*py dvdrip movies most of the times it copies them fully but when i run the movie it only plays like 1min or 10 sec or whatever...What is goin on here? Btw Win98 OS and it recognises my cdr as:ATAPI CDR/RW 16x10....Can anyone help me? Thanks.
