I have some sessions that were recorded on the mx2424 many years ago and backed up on Panasonic DVD ram discs 5.2gb LM-DA52. I want to get the tracks off to mix on another platform.

I have tried a few things and am open to whatever works as I haven't been able to locate a system locally that has the DVD drive.
1. I popped a disc out of the cartridge and put it in the DVD drive on my windows machine but it doesn't recognize or read.
2. Bought a DVD cartridge drive and it wouldn't read the discs either (connected to windows machine)

Is there a reason why they won't read in a DVD drive? (proprietary?)
How can I get the tracks off?
If I need an actual deck with the DVD drive attached does anyone know where I can rent one or a studio that can get the tracks off for me? (US)

Thanks for reading!
Mike
