doesn't sound improved... if you do a search under Toast 7 for Panasonic... you'll find that the locked problem is hardly new.
I haven't tried Toast 8 yet (was searching this forum with hopes that things had indeed improved with DVR created RAM disks) but all attempts at working with my DVR created disks in Toast 7 (other than complete disk copies of DVD-V disks) have resulted in crashes, failures (some that took hours and hours to fail) and other nasty experiences...
For now, I've only found 1 solution (or rather a combo of 2 other bits of software):
Purchase DVDRead from "Software Architects" ( unfortunately overpriced $50?!!) to properly mount DVD-RAM disks with ALL files visible. AND unlocked.-- (previously, I could only see/copy the obviously useless .ifo & .bup files.) further can't say anything great about the product, its a very hidden driver and am a little concerned that it's a tad funky.
Get "MPEG Streamclip": -- this a truly fabulous freebie, that inputs/outputs just about everything. The only downside to Streamclip, is that you need to manually set in & out points rather than choosing Titles, (and it is unable to pick up or transfer chapters.)
Sadly, although Toast 7 could see the Titles etc... on my mounted DVD RAM disk (but strangely unmounted it), it crashed after over an hours attempting to export a 14 minute title -- looked promising for a bit there) Haven't the patience to try again was really hoping to hear good news re Toast 8.
So for now, I'll stick with DVDRead + Streamclip. I'm also going to try a couple of other Apps which look promising (but bigger bucks) in Particular: 'Cinematize Pro' which sounds like Streamclip with a prettier interface but ability to select Titles.(You'll Still need DVD-Read, if like me you can't get Toast to deal with the files)
Should it matter: using LaCie d2 Lightscribe DVD with disks created by Panasonic DMR-EH75. OS104.8, QT 7.15, Quad G5
ONE NOTE: Supposedly Leopard will be able to read DVD-VR disks -- which will hopefully resolve this headache, and will likely aid Toast in dealing with VR files.
