MXO with iMac doesn't run smoothy

[manuel_default]

I'm working with iMac Intel Core 2 Duo 2,8 GHz with ATI Radeon HD2600 Pro with OSX Leopard 10.5.6. and FCP6.
I've installed many Driver Versions of the MXO - the only one, thats runs nearly good is 2.1.6.

Drivers above or under this version are worst. No Fields - no Sound, only plays 3-4 Frames and stocked.

But even with 2.1.6 - it doesn't work perfect: I get Fieldview and Soundoutput but there are many intereferences in Picture and Sound - after every 2-4 seconds.

I've tried it with XDCAM HD422 in a corresponding timeline an 1080i25 Output but even if I choose a PRORES Pal Timeline and generate Bars and Tone from inside FCP with PAL YUV Output at the Matrox I get these interferences. I've tried many combinations.

What can I do?

My only Hope ist to upgrade to Snow Leopard with FCP6 und try it again!?

So, I've updated to Snow Leopard and tried 2.1.7 that doesn't work at all - so downgrade to 2.1.6 again but it doesn't play without interrupts. Green blocks, white Lines, Audio stocks sometimes. I don't know what to do right now.

Cinema Desktop Preview over Matrox is working fine!

Cinema Desktop Prewiew isn't acually fine too.

I've tried DVCPRO50 in an matched Timeline with PAL Output - this is the first setting, that works. But I need HD output!

Sorry for this spamming.

I've just tried XDCAM HD422 Timeline with uncompressed HD YUV output - setting mirror on desktop is off - and Audio output is iMac Standard Output.
So my video and audio isn't in sync of course but video is working.

But thats not solving my problem...

Hi manuel_default,

Can you try setting the audio output to the MXO and then monitor it out of the RCA ports on the MXO, it should be in sync.
