Did somebody can guarantee in writing that AJA Xena 2k will work on Prospect 2k 3.3 environment as follows:
1. Real time preview (both still and moving) in Adobe PPro CS3 v.3.2.0 in HD resolution AND 2K resolution (with appropriate monitor, of course) (separate answer for both resolutions )
2. Import from external source in Adobe PPro (capture in cineform) OR with HDlink
3. Stand alone Preview (NOT within editing
There are several contradictory statements regarding this issue. I would like to have undertaking in writing that all that things will work as explained above.

Prospect 2K currently does NOT support the Xena 2K card. We intend support for Xena 2K but it is not done yet. We don't have a firm date, but hopefully by July.

In the mean time for the Xena LHe card

1. Real time preview of the timeline works in PPro CS3
2. You can capture through the LHe card (single link) from within Premiere Pro using Premiere's capture interface including with timecode support
3. I'm not sure what application is controlling the Xena LHe card for this question, so I think the answer is no.

Is the XENA 2k is supported NOT in 2k mode, but let say in HD mode?
Is the difference between these two cards 2k and LHe is so big that Xena 2k cannot be used in something like "hd/LHe compatible" mode?
Is the XENA 2k cannot be set from card settings to HD/LHe compatible mode?

Is your software cannot use only LHe features of XEna 2K?
I thing that XENA 2k is backward compatibile with LHe. This is the same thing like VGA card, all of them support native 800x 600, but only with special drivers and/or programs you can obtain maximum card resolution/acceleration.

Radoslav, unfortunately the Xena 2K drivers don't work like this.
