i didnt want to post a reply to your question in the other thread, as my other reply was really for the other poster. so i found this one. 
I just want to know why the hell it keeps jumping back to multi-read DMA 2.
can you post a screen shot of your ide controllers? have you followed all the suggestions? such as uninstall your ide controllers (not the secondary channel)? have you checked your ide cable? is it kinked, torn, burned, frayed, twisted, chewed by a gremlin…? be sure you have an 80 wire 40 pin cable? check the connections? are they loose? are the connectors loose? have you updated your drivers for your motherboard? have you updated the drivers for you ide controller? (i recommend using windows drivers). are you [B]100%[/B] sure this is only problem with dvdfab?
all disks I backup can’t all be dirty or scratched
i agree, i hardly ever get the error message. and when i do, i always hit abort, take the disc out and clean it (again if necessary). i do this just to try and avoid the trouble you have been complaining of. i set my dvdfab read settings to ignore 3 times and skip 64 sectors. if the read error cant be passed with three tries i figure it is unrecoverable. if after the cleaning (again) of the disc i still get the read error, then i will use nero drive speed to control the speed at which dvdfab will read the disc. which doesnt always make things better.
