[mythtv] dbox network load

Hi,

Now that I got my dbox2 setup as a recording source more questions pop 
up. Might be more fit for the user list but since dbox is only supported 
in latest svn...

The problem I see is that only very few channels are recorded without 
skips and quirks in the stream. Since my dbox only has a 10MBit 
half-duplex network card I guess it's only the low bitrate channels that 
work ok.
I'm new to the dbox and it possibilities (only got one to make it work 
in myth) but looking around at other recording software that is 
available I see they mostly use the UDP protocol to record the streams.
If I look at iptraf on my mythbackend while recording in myth I only see 
TCP packets comming in :
  Statistics for eth0
  Incoming rates:    4980.5 kbits/sec 



Anyone with more experience with ideas to optimize the network traffic? 
Would connecting the dbox directly to the backend with a cross cable to 
a second nic help?

Not sure if somebody (Levent?) is still working on the code.
Might it be better to use udp (like some other opensource recording 
tools for linux, like udrec http://www.haraldmaiss.de/, do) to capture 
the streams?

Steven
