DVD-R Iincopatability?

I thought you were talking about computer drives. If not, finalizing the disk is probably a good idea.

Does the file explorer in Windows show a list of the files that are on the DVD's?

Also, this data recovery program may be helpful.

Good luck. Regards,

This new format, among other things, resulted in DVD-R being unofficially referred to, in error, as DVD "minus" R. However, DVD "minus" R is not correct, according to DVD-R consortium recommendations; it is, in fact, a dash (i.e. DVD "dash" R). DVD-R and DVD+R technologies are not directly compatible, which created a format war in the DVD technology industry.

To reconcile the two competing formats, manufacturers created hybrid drives that could read both — most hybrid drives that handle both formats are labeled DVD±R and Super Multi (which includes DVD-RAM support) and are very popular.

I am not up enough on DVD to know if this could be a factor but something to look into.

It's possible to have DVD-R and DVD+R compatibility issues, but its very rare. If you set out to find a non compatible drive on purpose, it would be a difficult task.

I did finalize the discs, they are DVD-R. I also tried titling them with still no success, file explorer in Windows does not show or list them, they just won't read at all. Albert looks like you may have found the answer for me, as I feared that it may be a format difference and the only way around that would be to have them rerecorded (if that's even possible). Thank you all for the help and I can still give the data recovery program a shot too that might work so that I can get 'em to play on the TV.
