DVR-K04L and Toast 7

[easterhay]

Hi folks.
Got a 17" iMac G5, 250GB HD, 2GB RAM, 10.4.7 which had a Panasonic CW-8124-C DVD/CD-RW drive in working perfectly burning CDs with iTunes, Finder and Toast 7 Titanium.

Today I changed the drive for a PIONEER DVD-RW DVR-K04L. I have managed to burn an audio CD in iTunes, but when I try to do the same in Toast I get a message saying "Couldn't complete the last command because of a Mac OS Error. Result Code = -50" It also says the disc format isn't recognised, though it's the same make of disc which worked before the switch.
I've dumped the prefs file for Toast, and also managed to burn a data CD. Haven't tried a DVD yet.

Any suggestions as to what might be up?

Thanks y'all.

Sorry, perhaps I should add the System Profile entry for the drive is:

PIONEER DVD-RW DVR-K04L:

Interconnect: ATAPI
Burn Support: Yes (Apple Shipped/Supported)
Cache: 0 KB
Reads DVD: Yes

DVD-Write: -R, -RW
Burn Underrun Protection CD: Yes
Burn Underrun Protection DVD: Yes

I'm a dunce, so if there's an obvious answer, I'm likely to be missing it.

One thing to think about: you have to use CD-R's or DVD-R's, CD+R's or DVD+R's will not work.

I don't know if the writeable CDs I'm using are CD-R or CD+R (it's not clearly marked and I can't get them to register with Disc Utility when I put them blank in the drive, so not much help there), but I've tried creating a music disc with a CD-RW in Toast and get the same problem. Works for data, not for tunes.

I've done a search here and got the following result:

iMac G5 Rev.A 1.6GHz, 10.4.3, 1.25GB DDR.
Bootable and 100% compatible/supported. Ejects disks too far, sometimes they drop out. I still use Toast 5.2.1 and DiskUtil - runs smoothly

which seems, to my untrained eye, to hint at better odds with a K05 with Tiger. But I could be wrong.
