After some earlier problems and a new install of XP I got my New Teac 4x writer working using the following process:-
DVD Decryptor
DVD2One
Instant Copy ( With update from DVDR Help )
My First Disc , Lilo and Stitch went well and was processed in about 2 hours using Bulkpaq 1 or 2 x
I then transfered Signs onto the hard drive and also Road to Perdition.
When I try to write these it takes 2 hours just to do the initial read , and that is before it starts to write !
It has suddenly become very slow , only reading at about .5 to 1.5 Mb a second.
Does anyone know what the problem is ?
I have re - installed instant copy.
Please Help

Its not actually "reading" the data but encoding it to 4.0GB so it can be burned to a DVD-R. Mine goes at about the same rate and can take 2-3 hours.

You can try DVD2one on full copy, takes 20 mins to encode, however the quality wont be what IC would produce.
