actually both of my konas (kona 2 and LH) do 10-bit hardware downconvert on the fly. very high quality too.
you might be confusing the kona 2’s ability to do on the fly 10-bit upconvert which the kona LH does not have????
-
most people would consider HD availab le with the kona LH to be an advantage. if you are strictly doing SD, you will have more unembedded audio channels with the IO.
-
the kona LHe has both analog and sdi input as well as analog and sdi output. the kona 2 has analog output. why do you need to put a multibridge into the mix?
-
YES, the KONA LH can cross convert HD. whatever the other guy is trying to say, i really don’t know what the exercise was all about.
-
that is a cross convert and the LH works great with cross converting analog or digital sources to your choice of quicktime formats such as uncompressed 8 & 10 bit, DVCPRO HD, etc…. upconvert is SD to HD.

terrablock is raid 1 and 0, but you can do 3 uncompressed 1080i streams of realtime off of it as well as 2k, dual link, etc…. the real question is if you want shared. terrablock is a shared storage, where as XRAID is not. XSAN on top of XRAID is shared, but to get the same performance, you need to stack 3 xraids behind it. also there are some differences between file level and volume level sharing.
the terrablock works great with FCP, AVID and AXIO systems too, btw…

it is my understanding that writing to FCP’s realtime extreme architecture is the only official way for a card vendor to accelerate FCP. to my knowledge, AJA is the only manufacter who does this with hard–accelerating comrpessed HD formats like HDV, DVCPRO HD and IMX/XD CAM allowing the apple processors to focus on things other than uncompressing and playing such computationally intensive formats.
apple is developing it’s hardware accelerations, they are called dual core G5s, quad processors, etc…
looks like a pretty good development cycle, they’ll also hardware accelerate EVERY ONE OF YOUR OTHER APPS!

it clearly says “Support for” those apps. um, i would think it supports those apps. am i missing some capitalist conspiracy?

what card are you using now? maybe 10.4 whacked a driver? slow refresh or just noise?
in any event, if you are looking to upgrade, my ati x850 xt mac works awesome, so does the x800. you will need a $32 adapter, though to take the one adc to dvi, there is another native dvi on board.
bare feats has done test on both of them–they simply rock for performance and only take one bus. the strength of the nvidia is that it can run tw 30″‘s at once–but these will run a 30 and 23 at once which is more pixels than two 23’s obviously.
for installation, as your G5 tower stands up, the storage card goes in the pci-x 133mhz slot on the very top, the video card goes in the agpx4 slot at the very bottom and the kona card goes in either of the 100 mhz slots in the middle–either 2 or 3.
good luck resolving this issue!

[MitchJi] “issue is (IMO) if Steve will decide to axe PCI-X (remember serial ports) thus causing existing PCI-X cards to not work on future PowerMacs”
i would find other issues to lose sleep a higher priority!
