No, that's normal. Of course, you should have used Pauline's bigphysarea patch, but otherwise it's a sane idea, IMHO. http://www.polyware.nl/~middelink/En/hob-v4l.html http://www.polyware.nl/~middelink/patch/bigphysarea-2.4.4.tar.gz I often wonder why MPEG hardware designers are such dorks. It is pretty common place between them to ask for contiguous memory. I would say, 95% of requests for contiguous memory comes from poor hacks who have to deal with DVRs, PVRs, and such. Practically no other hardware is this idiotic. Not that it's impossible to do right, or anything. I think, stradis is sane. -- Pete
