[mythtv-users] HDTV Streaming over Wireless + Caching

Fri Mar 25 06:27:57 UTC 2005

I completely misread, I apologize.  Although I will admit my regular TV has
a hard time some times due to interference.  Hopefully soon I'll find an
antenna or something to fix this.

Don't get me wrong, I can't watch HDTV through wireless... I can only
watch non-HD as I indicated, those files are about 1-1.3 gigs an hour,
so they work quite well.
