Philips DVD+R very strange things happening

[RipTasticMate]

Just got my first DVD+R to try out in my new Pioneer DVR-106D, (DVD-R's are working fine by the way).
First of all Toast says there is 7.8Gig available from the Disc info menu, so i burn 2.7G of footage (including 2 menus and 20 stills, created in DVDSP1.5), Toast only gives me the option to burn at 2X, disc burns and verifies OK.
Then i place the disc back in the computer and it says disc unreadable ?!?!
So i place it in a stand alone DVD player and its works perfect.

Whats going on man ?!?!?!?!

Machine AGP G4 400mhz, Toast 5.2.1, OS9.2.2, 448meg.

Isnt that drive relatively new?

Perhaps Toast doesnt support it fully yet.

Maybe your first DVD+R Media was a lemon.

Could be a number of things.

Check with Pioneer and the Roxio forums.

Hope this helps.

My experience is its HIT OR MISS if your mac will be able to read a dvd+r disk.

DVD-r is more standard dvd media on a mac, and as such, having the disk work fine in a player but not your mac isnt anything new

lots of people experience this, well those with mac's that have +r burners either as a dual burner +/-r or a PC + burner in an external case.

Furthermore are you putting the disc into your computers built in drive or back into the drive that burned it?

This might have everything to do with it...

Friend has a Ibook G3 built in DVD-ROM/CD-RW drive. Officially this optical is not suppose to read any DVD+R and DVD+RW. Surprise, it reads both discs and all formats. If you +R is showing a error when place in the Apple issued DVD drive. then it means that that drive will not support +. If it is giving a error when placed back into the 106D, then thaty requires more investgation.

[RipTasticMate]

Yes the error is when its placed back into the 106D that burned it in the first place, how do you suggest i investigate this?

[Dennis1968]

That's a hard one. Try contacting Phillips Support and Roxio support. The burner should see the DVD that is burned! I do not have access to DVD burning on my friend's iBook G3 DVD-ROM/CD-RW only Try recreating the same exact problem using the same seps and programs with a DVD+RW. Nothing lost with a rewritable. See if the DVD is readabe in the Apple issued DVD-ROM. At least Eliminate the non supported + format on your MAC.

Sorry all im getting confused now, you mean +R/+RW is not supported the Mac? so does everyone have this problem?

[galactica]

thats the general assumption. No mac's come with +r/+rw drives.

The only way you can use these is like you do
1. +r/rw drive
2. toast to power the drive
3. the +r/rw drive to read the +r burned disk!

any "standard" drive in a mac cant read that +r disk!

likewise, any of the iApps wont burn to a +r/rw drive! As such, its not supported by the OS.

[RipTasticMate]

3. the +r/rw drive to read the +r burned disk!

Thats the problem im having, my pioneer 106 which is the +R i burn them in wont read them, but they work in standalone DVD players.

[galactica]

understandable. Its a "hit or miss" if your mac will mount the disk. Some do, some dont. Its all very odd if you ask me. BUT, thats why most mac users stay -r/-rw.

The only solution is to know it burns fine, you just cant use it in yoru comptuer, so dont use data dvd's then.

OR, sell your + drive and get a - drive.

I'm surprised to see you were able to burn a +R disc, since I've always heard that the Mac OS doesn't support +R format.

Interesting - it would seem the OS doesn't support the +R format (DVD-player, desktop mounting, etc) but a program like Toast can bypass the system to read/write the +R format directly (as long as you have a +R compatible drive like the dual-format Pioneer 106, or a dual-format Sony, etc).

I've noticed Toast already "bypasses" (for want of a better word) the OS when a blank CD-R is inserted (I don't have a DVD-burner) => if Toast is NOT running, and I load a blank CD-R - the OS prompts for whether I want to open it in the Finder, iTunes, or Disk Copy. If Toast IS running - the OS does NOT prompt me for what I want to do with the disk.

I actually burned a +RW and a +R disk with Toast using a Ricoh burner in an external Firewire case. The resulting disks were garbage when I tried to play them in my standalone dvd player. At this point and time, I would say that the Mac OS does not support the +R/RW format.

[dcsos]

My pal has the newest POWER BOOK with the 1x Matsushita burner
inside and under OSX it cannot operate on any onf the files burned on a PC in + format

THAT IS, it sees the files on the disc but won't play the DVD volume itself
as the FILES appear greyed out.....

The disc plays fine in any standalone player

Now RE-BOOT to OS9 (i guess its the second newest power book--still boots to 9) and VOILA.. we can see the files and opeate on them fine in 9..as well as play the DVD volume with PUCK (affectionate name for APPLE DVD PLAYER)

again
+r/+rw CAN be burned on a mac under the following conditions
1. Use of +r/+rw burner in an external enclosure or an external drive
2. Use of TOAST TITANIUM to use the drive.

Will these +r/+rw disks work in your mac?
NOT ALWAYS! 98% of the time, no. They may mount, and you may be able to copy the data back, but if its a DVD it most likely wont open apple dvd player, and even if you open the dvd player it wont accept the disk as correct media type/valid format.

Will they work in your standalone dvd player?
YES! As long as it takes +r disks.

Can you burn DATA DVD+R/w on a Mac?
YES! BUT, you most likely wont beable to access the data on your mac.

To summarize
You can burn dvd+r/w on a mac if you have the right set up.
You most likely (98%) cant access the burned +r/w disk back on your comptuer.
You MAY! (2%) beable to mount them, but using them is another question
