DRDeviceSupportLevel
I've found that by adding a DRDeviceSupportLevel key to the DRDeviceProfile dictionary in my device profile, I was able to make my device profile stop working. That tells me that the framework is looking at that field, and if we ever figure out the right data type and value for that key, we can get a higher support level, and hopefully enable burning from Finder and iTunes. I looked up DRDeviceSupportLevel in the developer documentation and found that there are 5 levels: DRDeviceSupportLevelNone, DRDeviceSupportLevelUnsupported, DRDeviceSupportLevelVendorSupported,
DRDeviceSupportLevel
I have been very successful installing the EMPREX DVD Dual 4X +/-R +/-RW (I got it for $89 at Fry's!). This drive is the same thing as the BTC DRW 1004IM OEM drive. So far, it works with Toast 6, iTunes, iDVD, iPhoto and Disk Utility (Not Finder).
Prior to installing the profile, 'drutil info' reports the following: Vendor Product Rev DVDRW IDE1004 0043 Interconnect: ATAPI SupportLevel: None Cache: 2048k CD-Write: DVD-Write: Strategies: The profile file for this drive follows:
To get around Apple's block on 'Unsupported' drives, I used the modified version of DiscRecordingEngine available at Bidouille's web site.After installing the profile file, 'drutil info' presents the following: Vendor Product Rev DVDRW IDE1004 0043 Interconnect: ATAPI SupportLevel: Unsupported Cache: 2048k CD-Write: -R, -RW, BUFE, CDText, Test, IndexPts, ISRC DVD-Write: -R, -RW, +R, +RW, BUFE, Test Strategies: CD-TAO, CD-SAO, CD-Raw, DVD-DAO
DRDeviceSupportLevel
DRDeviceSupportLevel is not a supported variable in the DR Profile. I did extensive research of the code to determine what exactly could be defined in the profile. Bellow is the list I came up with.
There are some interesting options in there! For instance, 'DRDeviceAppleDVDAuthoringDevice' might be interesting... :) Note that I set ~ where I know the default. Any illegal item or illegal value will disable profile.

DRDeviceSupportLevel
I believe all of this works and I would love to be able to use my Plextor PX-708UF drive with my Ti-G4 powerbook. I am one of the "Mom and Pop" types that needs more info/help on implementing these hints. I am a user but not a programmer. Any help would be appreciated. Keep up the good work. |
