One of the more difficult problems to trouble shoot in a home LAN is duplex mismatch. Most Ethernet switches used in home LAN applications are unmanaged -- 'plug-and-play'. It's hard or impossible to determine if the switch port and NIC have both auto-detected the same duplex setting. The symptom of duplex-mismatch would be frame loss, resulting in missing packets, resulting in video and audio stutter or break-up.

The HDHR does provide a way to verify the Ethernet NIC speed and duplex.

C:\Program Files\Silicondust\HDHomeRun>hdhomerun_config 101A5A4B get /sys/debug
mem: nbm=117/104 qwm=15 npf=622 dmf=282
loop: pkt=0
t0: pt=9 cal=2048-11381 bsw=155/435
t1: pt=9 cal=2048-10867 bsw=155/435
eth: link=100f
In the above, I used the command prompt on my XP box to 'get' the 'sys/debug'. The last line of output indicates the NIC is running 100 Mb/s, full-duplex.

It's possible too, that the tuners in the HDHR are bad...

Your internal tuner will not have the LAN connectivity issues to deal with.

Glad to hear you are up and running.
