Tweaks for hd with mythtv

The maximum receive socket buffer size defaults to 128k(131071).

To increase the max buffer size to 1MB:
sysctl -w net.core.rmem_max=1048576


echo 262143 > /proc/sys/net/core/rmem_max
echo 262143 > /proc/sys/net/core/rmem_default

To confirm the new max buffer size:
sysctl net.core.rmem_max
