I'm using the 128 meg and very happy with it on dual display LCD 19" and 17" and external Sony 13" NTSC monitor. Also the card will output DVD and render previews to "S" video. When I do a small preview render to media player it will preview out the "S" bideo buss to another position on my video distribution unit so I can see almost what the final render will look like on NTSC. So effectively it is 4 position capable.
There were never any problems but the software takes up about 22K
on the memory usage.
Reccommend highly.
