If the best you can do over tcp is 1MB/s then first off, you should
probably transcode your programs. MPEG2 from my ivtv card is about
1MB/s, transcoded it's 250kB/s. The latter I can watch over wireless,
but not the former. YMMV.
Second, use nfs over tcp. I had the same problem using standard nfs,
even on a 100Mb wired connection. Try these options in your
You shouldn't need nfs to find recordings. The frontend gets a list
from the backend process, and if it can't access the recording through
the filesystem, then it will stream it from the backend process.
mythvideo can't use this method so it does need nfs.
