What kind of issues are you guys having converting from dvi to hdsdi? I think I will more than likely be doing this in the not so distant future and since you mentioned issues I thought I would ask. On a side note I have noticed that matrox is releasing some new sdi output cards for mac but I dont know if they support openGl etc.

Here is a link: http://www.matrox.com/video/en/press..._multi_io_mac/

If you read the article it would seem that these devices are targeted toward what we do with catalyst. You guys have any input on these?

There are also input cards and cards that do i/o.... would be amazing if these were actually suitable? your thoughts Richard?

BTW... these fit in an xserve supposedly
