[mythtv-users] HDTV Streaming over Wireless + Caching

[Richard J. Sears]

Is there any way to deal with this by caching to the frontend to help
this problem out...?

So you hit the "play" button and it starts a 3 to 5 minute caching
process (which should be enough) and then starts playing.

Wireless is the only way for me to get there.

What about "non-HD" cable channels..what is the requirement there..?


Thanks
