[mythtv-users] LiveTV from capture card in SBE/FE is buffering like crazy!

[Josh White]

Sorry, I guess I missed that.  On my previous read, it looked to me like you
were trying to avoid buying a new wireless g adaptor.

I had a similar setup, but I found that the wireless G from my netgear
router was not reliable enough.  I eventually gave up on that and ran cat6
cable and now have a 100Mbit network between my frontends/backend.  Now I
have no network issues that I notice, and since I used cat6 (which I got for
free, thankfully) I can just replace the router/switch I use, and I'll be
able to upgrade to gigibit when I upgrade to HD in a few years.  If you are
set on using wireless, you can try transcoding the signal to a lower quality
level so you reduce the bandwidth requirements.  You could also play with
your priority settings on your tuners so you avoid the situation where
you're recording on a local tuner, and need to watch live tv on a remote
turner.  You could also adjust the location of your wireless router, adjust
antennae, or anything else you can think of to improve the performance of
your network.

FYI, I normally can watch live tv form my remote backend using a wireless
laptop, through 2 walls (where I have a microwave directly in the path).
The total range is probably 30 ft.  I don't do this very often, and it does
stutter on occasion, and it is very slow when I first turn on the tuner (it
takes 10-15 seconds to buffer before it starts to display live TV).

Another thought occurs to me.  Are you trying to send data both directions
between your MBE and SBE while you are trying to watch TV?  As in, are you
writing any data from your MBE to your SBE, while trying to stream live TV
from your SBE to your MBE?  That could over tax your network as well.  I
suppose you could be using your MBE to record, and your SBE to transcode,
commercial flag, etc.  It seems unlikely, but I thought I'd ask.
