[AG-TECH] RE Access Grid Hardware, expensive

[Michael daley]

Hi Marie-Noelle
	In answer to your questions
The video capture was originally specified by Argonne as being LINUX.
I did try video capture under XP but had big problems with XP using  more than one hauppage card. ( It saw 4 cards but could not use all 4 properly. I eventually gave up and went back to RedHat. Which has recently been upgraded to Fedora.
I have tried using XP since for capture but have trouble with multiple cards be it Hauppage or Osprey.
I understand others have got it to work under XP

The Audio was originally LINUX but we changed to XP for no good reason. It works under both platforms and we have machines running Fedora and audio with no problems.

All the best
Mike
