Panasonic Matshita CW-8121 firmware upgrade

I have this combo driver, but I have some problems. I can’t read lot of dvd, (+R no one) but I’ve read that it’s possible. Also it is very slow while reading dvd and cd and sometimes they are rejected.
My os is Windows Xp Pro
Thank

You can find a couple of firmwares here: http://forum.rpc1.org/dl_firmware.php?download_id=252

Please make sure that DMA is enabled for the drive.

thank you. But how I can make sure that DMA is enabled for the drive?
And how can I use real dos? I don’t have any floppy drive on my pc, only that drive
In the end, is sure that after this upgrade my drive can read dvd+r?

No, I doubt that a firmware update will help your problem, but it is possible. You can create a bootable CD to use to get into DOS.
