I was waiting for feedback on the change of MUX selector values; since everybody was silent, I committed it now. Anybody with an angle on the DMA problems? To repeat: (1) A single steady vertical line when the fxtv window is in some position in the upper and lower right corner of my screen (1600x1200x16 bit) - the rest of the window work normally. This one seems likely to be a splitting problem, IFF the split is done as to rectangles vertically. It seems to be related to the size of the window; I've had some problems repeating it at will, but get it from time to time. (2) DMA to the wrong position (horizontal offset) when the screen is 32 bits deep. I don't have any clue as to whether this would be an XFree86, brkt (kernel driver) or fxtv problem. (3) Swapped lines (?) I had something that looked like line interchange once, but it went away when I increased the size of the window. Probably out of sync interlacing hardware. Not reproduced, and might be just 'sleight of the eye' - I have an extreme resolution, so it is hard to see. If any of you have any opinions/information that help me on where to start looking for the causes of these problems, please step forward. Eivind.
