Replacement DVD drive for DVR-640HS



I have a Pioneer DVR-640HS region 1. It is over two years old. Recently I’ve experienced the DISC ERR front panel message along with COULD NOT COMPLETE COPY on-screen message when burning a disc from HDD to DVD.

Following instructions I’ve found here, lens cleaning does not seem to help.
The harddrive recording/play and timer functions are fine, as is DVD playback of commercial and recorded disks.

So the next option is to replace the DVD drive itself. I’ve had Pioneer drives die in PCs, weak laser, etc, so I think this could be a possible solution.

Does anyone know what type of DVD drive works in these machines? Will any OEM drive from a computer shop fit?

Thanks for any info.
