Ah, interlaced, that makes sense.

Yes, this was on the MythTV internal player.

I'm going to try playing around with the troublesome transport streams a bit to try to narrow down what characteristics about them are making things hiccup (suggestions for what to try welcome), and if I can't figure out anything I guess I'll have to figure out what might be adequate to try in a PCI-based card with DVI-out. -Jerry _______________________________________________ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
