I can open text and jpgs from the dvd on the pc. I don’t have Word on the pc at the moment, so I couldn’t test those but I assume they will also open.

Yes if the PC can read the disc then you’re fine.

I really don’t get the hybrid issue now. Maybe it was a problem before mac os x and the hybrid burn feature is for earlier mac oses?
[/QUOTE]
Yes it’s for older MAC support as I said before, there’s no problem w/ os x it will read 9660 fine.

Burnz says it burns “strict ISO-9660 discs that anything can read”. Does “strict” mean w/ or w/out the apple 9660 extensions? Anyway, it seems like current burning software for the mac will burn discs readable on a pc.

9660 never used to be supported on older MACs and is not an Apple format so not sure about that? MAC doesn’t use file extentions like windows so not sure what you mean? Either way you don’t need to worry about it.

Does Toast burn multisession dvds and allow you to save compilations? There doesn’t seem to be a trial download anymore.[/QUOTE]
Not sure about multi-session DVDs as it’s really not reccomended. You are better off burning a full disc in DAO and close it.
