[mythtv-users] HDTV Streaming over Wireless + Caching

[Todd Tidwell]

Then you are incredibly lucky with your wireless.  I've tried both 802.11g
and 802.11a networks and I still have issues.  I'm right on the skirt of
having enough bandwidth to basically move 6.3 - 7.3 gigabyte files from one
wireless machine to another via wireless.

For me, one machine has a 60% connection and the other an 80% and that can
be +/- 10% each way for either machine.  While that's right on the border,
its not quite enough.  My hope has been that some of the transcode stuff
will eventually get changed (or explained well enough to me that I can
change it myself) so that I can transcode down from the huge resolutions I
am forced to capture in to 720p resolutions since I can't do more than 720p
on my TV anyway.  That will at least get the amount of data down a bit.

Meanwhile, the first poster is probably right in that it would be nice to
have some sort of buffer beyond what is currently used in the frontend as a
setting that could be used on a frontend by frontend basis to solve problems
like this.

Non-HD streams nicely over 802.11g, I get dropouts sometimes, but only
when I'm 2 floors from AP
