Been searching over at the forums at osx86scene and it appears as though some other individual experience the exact same error but with iDvd. I PMed him to provide some more feedback on his problem. The reply to his post hinted at EFI being the problem. If that is the case, I wouldn't know where to look to resolve this. Looks to me to be kernel related.
By the way, I installed Quicktime 7.3 on Leopard. Same issue.
That would make some sense; iDVD is the one application I cannot run on my Hack (JaS 10.4.8 upgraded to 10.4.9). It's supposedly crashing on startup (it wasn't even provided in the JaS install if memory serves). I didn't know it was related to EFI (bypass). Since we don't have it (EFI), it may never work on Hackintosh; it's too obscure an issue so it won't get kernel hacker time. I tried quicktime 7.3 as well to no avail.
I have an additional workflow workaround for you, one that doesn't involve any hardware. It does involve Windows (VMware Fusion is fine). You have a Sony cam don't you?
1. get hold of Sony Vegas Pro 8.0a
1.5 install it in Fusion; this way you can use shared folders between OS X and WinXP
2. Import your AVCHD clips; Media Manager is great
3. if you happen to like it (the NLE), that's that - it is quite capable, but annoys me for some reason.
3.5 basic trimming and clip selection in Vegas
4. ...this is the way to FCP --->
5. You have two options:
5.a) render out to uncompressed in a QT container (u need to install Quicktime on WinXP) -- huge pain in the butt(space) - 15 sec of AVCHD --> 2,2 GB uncompressed; you better have stripped RAID0
5.aa) this time in OS X use Compressor to transcode to ProRes 422 HQ. Don't deinterlace in Compressor, not so good. Now you're at the same place as if you paid for Mac hardware. You need to get all the settings right (watch out for pixel aspect ratio).
Okay, this is the MXF route. Render out your clips in Vegas as Sony MXF; use a Custom preset (save with new name) bumping the bitrate to 35 Mbps.
5.bb) Guess what, the above is XDCAM HD, so what follows is the XDCAM HD workflow for FCP.
5.bbb) get XDCAM_Transfer_1.1.dmg from the Sony site. Sony apparently has nonstandard MXF so it needs to be rewrapped(?) with this tool for FCP to see the clips.
This is where I'm at right now, trying to get this otherwise simplistic tool to do what it's supposed to do; maybe I'm tired...
I can see the clips in the XDCAM Transfer tool, ex:
Video format: MPEG HD (I believe this is long GOP MPEG2, no longer AVC)
Bit rate: 35 Mbps (VBR)
but pressing Import doesn't seem to generate new clips. I'll update when I have it working, it's probably about which directories it's configured to write to. I'll have to read the user guide...
