Just a little more info.
The lost Firewire I/O is only on systems that are upgraded from 10.3.9 to 10.4.x
Systems with a 10.4.x clean install do not have this problem.

The UL4D should be in the top slot, the PCIX133 slot, with the correct firmware (I think it is 1.4.2) and 3.40 driver.
The KONA-SD should be in slot 2 or 3 by itself.
This configuration works. We have this configuration last December before we installed the KONA2 cards.
If your G5 is one of the PCI only machines, it is not going to work. The PCI only G5s canot pass data form one PCI device to another fast enough for uncompressed video. You should contact our reseller or AJA for details.

OK…
Have you swapped cards, and does the problem move or stay in the G5?
What other cards do you have in the G5?
What disk array are you using?
I ask these questions because the KONA-SD is a 33Mhz card and it was not designed with a G5 in mind.

CaptainFTP is the best.

Ok, I just cannot let this one go without a comment.
SD-Connect is not an AJA product, it is a Convergent Design product. It is infact an I/O device that may conflict with other I/O devices installed on the same system. I would not expect AJA/Apple/ConvergentDesign to support the use of the two I/O devices at the same time. AJA has done a great job in getting their iO products to work with their KONA cards, and the could do this only because they control the software drives for these I/O devices.
We need to give our great expectations a reality check.

“Actually, you should be able to see a difference using that method since you’ve doubled the compression. You take a DVCPro HD tape which is already compressed. Run it into the Kona 2 and ask it to compress it again. I can see the added artifacts when viewing an image that has been captured this way.”
“If you’re going to come in HD-SDI, then stay at 720 uncompressed, don’t apply the DVCPro HD codec. I’ve done the side by side comparison of Firewire DVCPro HD capture vs. HD-SDI Uncompressed capture of a DVCPro HD tape and they are identical. But apply the DVCPro HD codec to the HD-SDI capture and there’s a difference.”
Walter, I respectfully disagree:
The Firewire DVCPro HD capture vs. HD-SDI Uncompressed capture of a DVCPro HD tape are not identical. The Uncompessed HD-SDI of a DVCPro HD tape is better than the FireWire output of the same tape. We’ve done split screens of both and the 720 Uncompressed looks better than the DVCPro HD. The Graeme Natress article supports this although in SD vs DV25 only.

It is our observation that the Uncompessed HD-SDI image from a DVCPro HD tape (Panasonic 1200A) is in fact better than the same image from the FireWire out of the same VTR. Thus allowing the second compression back to DVCPro HD thru the KONA-2, resulting in an image as good, but not better than, the image that came in from FireWire.
We did these test to justify purchasing the FieWire option in the Panasion deck. We could not prove that the option was needed if we had theHD-SDI to KONA path.

We have done our own little eye to eye testing and we agree with Graeme Natress, DV sources ingested via SDI and (saved as uncompressed 8/10bit ) looks better than DV sources injested via FireWire. But of course the SDI files are much larger.
However, we also believe the SDI/HDI into the KONA2 and down sampled to DV25, DV50, or DV100 “looks” the same as FireWire in of the same sources. We test this with a Panasonic HD1200A that had both the FireWIre and SDI/HDI options installed. We tried it with DV25, DV50 and DVCPRHD (DV100). We could not detect a difference in the Decompressed HDI -> Recompressed DVCPRO and the FireWire -> DVCPRO direct.

The issues is not 4.5 vs 5.0, it is OS10.3 vs OS10.4.
You can run FCP 5.0 under 10.3.8 (or9) with QuickTime 7.1, on you dual 2.7 with the current KONA2 drivers.

The Kona DVCPRO Hd 720p 59.94 output will playback a 24p sequence.

FYI
720p 23.93 conversion to NTSC-SD 29.97 works just fine on the KONA2.
