MATSHITA DVD-RAM UJ-875S - Anyone know which media are compatible with this

Question

Hi,
I bought the Matshita DVD-RAM US-875S from the PowerBook Guy and installed it in my G4 Pismo. I have corresponded with their support--who reply, but without actually answering. On PowerBook Guy's site, the thing is described as a Superdrive DL DVD-R-RW burner/player. I know this is a very basic question but I need to know if that means it will burn and play ONLY DVD-R and -RW whether DL or regular. I've asked them and they just say "It supports several different media. Ask on the Matsushita site."
Okay, there is probably some Matsushita site with that info, but I can't find it. I've gone through four pages of Google searches and haven't found a Mats site that has it. Panasonic Customer Support--or Parts--doesn't find it after a search.
System Profiler says it will write -R, -RAM, -RW, +R, +RW, +R DL. That's great if it does, because +R DLs are much easier to find than -R DLs. But why would PB Guy call it a -R-RW burner/player instead of telling you all the capabilities?
I found one site (CDfreaks.com) that says write speed as follows:
DVD-R 8 x
DVD-RW 6 x
DVD-R DL 4 x
DVD+R 8 x
DVD+RW 8 x
DVD+R DL 4 x
DVD-RAM 5 x
Note that it give DVD-R DL, which System Profiler does not. And DVD+R DL which PowerBook Guy does not. Does anyone know what the capabilities of this drive are, or where I can find a definitive answer? Thanks for any help you can give. Giles

Answer 1

Okay, for anyone who's interested, here's what I found on a British site called TheBookyard.com.
The Matshita (or Panasonic) UJ-875 slimline (I assume that's what the S means) is a replacement drive for the discontinued UJ-85J, the only difference in the specs being that the newer drive is slightly faster on the DL writing:
Specifications
Interface: IDE/ATAPI, Ultra DMA Mode4
Buffer: Memory 2 MB
Loading: Method Slot loading
Dimensions: 5.07” x 5.03” x 0.5”
Read Speeds: DVD-ROM 8X, CD-ROM 24X
Write Speeds:DVD-RAM 5x, DVD±R 8X (SL) 6X (DL), DVD-RW 6X, DVD+RW 8X, CD-R 24X, CD-RW 24X
So if it really does all this (haven't had time to test different media) I'm happy. My only question now (except re the error message in a separate post) is: Why does PowerBook Guy call it a DVD-R,-RW?
