After looking at this problem for several days, I have noticed some patterns. I hope this helps.
1) Only sports and news broadcasts seem to exhibit the problem frequently. 2) Movies and old TV reruns never or rarely exhibit the problem. Commercials exhibit the problem only if high contrast and sharp color transitions is used. 3) The sync failing is sensitive to graphics overlays, especially text. This high contrast is rare in natural images, so it may be avoided for technical or esthetic reasons in most programming. Only a small bit of graphics is enough to trigger the failure. It stops as soon as the graphics disappear. 4) One news station mentioned that they broadcast in HDTV. This suggests a possible connection with the conversion process from HDTV. News and sports broadcasts seem the most likely to use HDTV. _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
