When the fxtv window is overlapped by some other window the video is only updated about every 30 seconds. When using mplayer's bsdbt848-driver I get an undistorted image but also choppy video. I wasn't able to test it with xawtv since it is still broken on 5.x. This is a regression over 4.x, where everything works flawlessly. I have done some testing with different versions. I can was able to reproduce the problem on: -FreeBSD 5.0-RELEASE -FreeBSD 5.1-RELEASE -FreeBSD CURRENT -NetBSD 1.6.1 However it does does not occur on: -FreeBSD 4.3-RELEASE up to 4.8 -FreeBSD STABLE I assume the problem lies within the bktr-driver since it also occurs on NetBSD and it must be something which has been changed in -CURRENT before 5.0-RELEASE and not MFC'ed yet because -STABLE still works fine. >How-To-Repeat: Try fxtv or mplayer on given FreeBSD/NetBSD versions and hardware. >Fix: n/a >Release-Note: >Audit-Trail: >Unformatted:
