I use to write nuvexported files into CD-Rs to watch them using MPEG4 CD menu item (R4D1 + 0.20) and it works fine. I can watch regular DVDs, too.

But, if I write nuvexported or mytharchived (in the same box) files into a DVD-R, my mythbox can't mount it.

When I try to manually mount it, the result is:

In my home-office machine, running Kurumin Linux, I can mount the discs and play the files.

My drive is a Samsung Writemaster, if this make some difference. I've swapped the DVD drives in both machines and the problem persists only in mythtv machine, so I believe it's not the drive.

Is there another way to mount these DVD-Rs?

Thanks in advance.
