It seems that there is something on the DVD-RAM which the Panasonic machine needs to see and the computer overwrites it.
Deciphering HDD formats for DVD recorders is giving me a little insight to this problem. I am no "expert" but those are my credentials.
DVD-RAM is a form of VRO (or VR) formatted media which means it was intended to be used as Edit material, not Playback material. So they had to adopt a Hard Disk "like" format.. but at the Time of the MtFuji working group, Microsoft was both involved and suing the heck out of Linux and Camera manufacturers for using anything like the FAT filesystem.. this lead to Mr. Gates famous video interview with an investigator in which he said ('what do you mean by the word - concerned?')
Anyways, Toshiba, Pioneer and et.al. used the OSTA groups UDF as their "file system" which was an open format, but its a (container) not a a whole disk partition. Outside this container is a Volume format that generally sits at the Top and often at the Bottom of the drives addressable "logical blocks" they surround and cradle the UDF.
You can create a UDF, just like you would on a Windows hard disk, but Windows is going to assume you want a "partition" in the Windows "way" of partitioning the disk to hold that. That means an MBR or DOS Partition style table. Panasonic and others could not do that without fear of being sued.. so they did not. In fact most companies used the EVB, or evaluation board reference partition and file system format provided by the development environment. For DVD-RAM they tweak that back towards UDF compliancy so that they could use the DVD-Forum features and appear to be one happy family. The volume partition format however was deliberately (not) DOS or Windows compatible.. hence why they won't work with that when formatted with something from Microsoft. - Monopoly protected.. but darn wouldn't it have been great to get the royalties from all those DVD recorder and camera sales? All we got was one round of lawsuits.. one and done.
So sounds hopeless.. right?.. not exactly..
Panasonic made DVD recorders and Cameras.. and were just as wary of Microsoft on both platforms.. so they started writing their own software.. well actually it was "out-sourced" and re-branded as Panasonic software for their cameras.. but it was just as useful because it followed their Volume formats. And it ran on Windows.
It would be a research project I don't have time for now.. but The Panasonic DVD-RAM "camcorders"... the ones that allowed you to insert a (mini) DVD-RAM disc could quite possibly come with the Panasonc DVD-RAM format and reader software you need to run on Windows in order to format your DVD-RAM discs for use in your Panasonic DVD recorder.
That would be my first guess, if that did't work.. you'd have to turn to something in linux-land.
Everyone at the time was trying to extract profits from 'thin air' and thus it was a hostile envionment. Compatability was dangerous.
