Hi, > Can anyone save me the trouble of going thru the zapping source code, > and tell me what zapping does that removes the artifact? I'm sure the > code is enlightening and entertaining though :-) You are right, it is utterly enlightening ;-) There's nothing there that could make a difference, except if you are using the XVideo extension. Zapping cannot use it (it uses normal overlay), but xawtv can. Does xawtv -noxv make any difference? If it doesn't, it must be something I wrote while i was on crack, cause i cannot remember it :-) Regards, Iñaki PD: I'm playing with evolution 0.5.1, please bear with me if the text looks strange :-D
