While using either DVDx Copy Xpress OR DVD decrypter with DVD Shrink, the disk has serious errors, locks up, shows a REALLY long time to completion right when it is nearly finished writing the disk. I have NO problems reading the disks with either program, just burning. I recently flashed my Mitsumi DW7801-TE to upgrade to the new 8x speed disks (even though I was having no problems...may have been stupid who knows). Also I think maybe a driver has been changed from PIO to DMA though I don't know if this would make a difference. Please help, thanks
