Subject: DVD-R non readability in 10.2.4
"We have confirmed that the playback problems with some DVD-R disks is related to [b]permissions[/b]. I record disks on a Panasonic DMR-HS2 recorder and these don't play back unless I run DVD player as [b]root.[/b] "
I blame Panasonic for not writing with the correct permissions, but this should be easy to fix for apple. Maybe there would be away to ignore permissions on the DVD's?
I have burned a DVD_R and a DVD RAM re recordable on a Panasonic DMR-HS2 recorder but when I insert this discs into my G4 DP 500, it either will not see the disc or tell me the format is unreadable by this computer....
Yet when I go to the disc utility, it will see the disc.
I tried Wally Rodriguez approach of logging in as root, but still no difference. The Panasonic DMR-HS2 recorder is an awesome machine, with great quality of recording and flexibility. I just need to be able to bring these files back to the mac for editing. Do not know what I am doing wrong.
and also saw something about Region Code setting in that page above (use the Find function for easier/quick search - use "DVD")
could try a different Brand of blank Media
here's the specs for that Sony in case others want to see the features/capabilities
