DVD-R verification problems with Pioneer DVR-106D in OS X

[milocoon]

I can burn a DVD-R and have it verify if the data burnt is less than 3.9Gb in total on BulkPaq Tango (2X burn speed) reliably !
But if the data is between 4.0 and 4.3Gb then I get verification error or sometimes the progress bar in Toast just sticks at about 90% verified.
Using Toast 6.03 in Panther 10.3 with a Pioneer DVR-106 with firmware 1.07 with buffer underun protection on.
Anyone any ideas on this, I get more coasters at 4X speed than at 2X but the same drive and same media are fine in a friends PC at work and he always burns successfully at 4X ?

Burn a test on your media at 1x speed.
I know, I know, why burn 2x media at such a
slower speed, that's not what I bought it for.

But, as is the dvd caveat: "Different Media acts indifferent
with diffrent brands of burners."

In my native DVR-104 Pioneer, Apple media is the only media I can get
to successfully burn at 2x and verify at 2x. If I burn Maxell, Imation,
Fuji, or Verbatim at 2x and try to verify, I get the same errors you mention.
And yet, the DVR-104 I use at work can burn 2x to these media and
verify with no problem!!!

Just try one to 1x media and make sure Totast 6 can verify.
That way, you can rule out problems with the drive.

I've got a AO/4 in my iMac running 10.1.5, and have been having these problems for weeks, now. When I'd burn any media at 1x..... No sweat. The problem seemed to arise during the verification process in Toast. Now my brother uses, exclusively, a pc, and he has no problems with verification, because he *never* verifies. Instead he "finalizes" the discs that he burns, and they *all* play on any set top dvd player. What's the difference between finalization, and verification, and why don't, as Mac users, have the option to either finalize, or verify?

Thanks for the replies guys ! Last Night I`ve gone back to a clean install of OS 10.2.6 (I had kernel panics in 10.2.8) and used a burn patch from xlr8 website to enable "full burn support" for my 106D(if you want this its in the "FAQ" section). I`m also back on Toast 5.2.3 which has the burn proof compatiblity with my drive. It was easy as I had a Cloned Image I had saved on my other HD using Carbon Copy Cloner.
I`ve been testing some Ritek 2X DVD-RW media with verification on and at 2X I`m getting no errors on these at all, I`ve even managed this on a 4.37 Gb VIDEO_TS.
Toast 5.2.3 is fine
I`ve also used DVD-Imager 1.2 to image that same VIDEO_TS folder and using Disk Copy burnt this Image perfectly using the Apple Disc Burner at fastest (it was 2X or about 30 minutes) and this is fine.
Tonight I`ll try the Bulkpaq Tango (4X) DVD-R at 2X and then at 4X to see if the problem is fixed, if it is then its either Toast 6 or Panther !
The guy asking about verification and why to use it ?
Verification is very important as it checks what you have burnt against what you should have burnt. For DVD Movies you may have heard people complaining about watching a movie and couldn`t watch the last ten minutes as the movie froze (this is usually as the first 3.9 Gb burnt perfectly but the last 0.4Gb after this had read errors. The DVD Player doesn`t know what to do when it reads an error so stops and the movie freezes or stutters)
Finalizing is the same as closing a disc and Toast doesn`t do Multi-Sessions on a DVD Movie disc so it finalizes or closes the DVD after burning automatically.
Hope that helps explain things !
