Firewire Video Out in 64bit mode doesn't work (32bit ok)

Hello!

Just as I said in the subject, I’m installing a new Nuendo 5.5.4 on an iMac, and as I can’t plug my Intensity there (at least, the PCI model) I went with a Canopus TwinPact 100 I had around.

Nuendo 5.0 was fine with it (32 bit), Nuendo 5.5.4 in 32 bit mode also fine, but If I try (which is my purpose, anyway) to run Nuendo in 64 bit mode, there’s no firewire video out.

I mean, the option is there of course, but nothing comes out. I then switch again to 32 bit mode, everything’s running.

(And, by the way, now that I had the chance to compare Nuendo 5 and Nuendo 5.5 video engines side by side, what a great upgrade N5.5 has been!.)

Any chance to make it work in 64 bit mode?

Best,

Jorge
