Well, I'm asuming that USB 1.1 is 12Mb/s so divided by eight would be 1.5 MB/s
And DVD 1x = 1.32 MB/s
On "paper" it looks okay... I'm not sure how much overhead USB uses...
Looking at a couple of manufactures, no one say that you can play DVD on 1.1
They max out at 6x CD read...so about .86MB/s (not fast enough for DVD)
I'd say you're out of luck..
Perhaps you have a good friend that will burn the DVD's to VCD format so you can still watch them ...
