I also have had this problem specifically when playback recordings. I have less of a problem when watching LiveTV, so I guess there is more overhead when watching recordings. My WiFi network can sustain about 2.00MB/s and that is with an Apple Airport Extreme Base Station. Hope someone can help fix this? Thanks. _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
