This (first alternative) sounds related to the problem I had with DVB; I got visible corruption of video memory when using xawtv on the DVB video device using Xv on a G550. The cause might lie in either of: - Hardware/AV7110 firmware - Kernel DVB driver (probably: AV7110 videodevice part), tried many versions - Xfree86 XV-over-videodevice driver, tried several versions - Xfree86 MGA driver, tried several versions Never found the cause, but the problem went away with disabling the Xv extension (now using video overlay mode).
