How to test dvd copys?

When i copy data i copy all the dvd content to hd to check any crc but i believe i cant do that with dvds… so whats the best way to check dvds quality with nec drives (who cant use quality tests :frowning: ) :stuck_out_tongue:

why can’t you do that with dvds?
how about a nero dvd speed test.

the one that give a lot of info and an overal score for dvd? nec driver dont work with it :frowning:

you can do the following

fc (or windiff for windows)
there are various file compare programs you can use


you can stop worrying as nec writers are beyond compare

i said speed test, not quality test
