Both the MediaMVP-HD and the MythTV Backend are Directly connected to the
same 16 Port 10/100 Switch. Telnetting into the MediaMVP-HD I can see the
Kernel is reporting 100 Full-Duplex:
eth0: link up, 100Mbps, full-duplex, lpa 0x45E1
The Video stops completely within a few Frame, the Audio remains Choppy
and it "Intermittent" for a while after that. Curiously the MediaMVP-HD
is unable to "Resume" past this 10 Second "Wall"???

My MythTV Backend has a pair of Hauppauge HVR-1600 Tuner Cards which use
Hardware Encoding to generate MPEG2 Files and my understanding was the
MythTV Backend simply records those Video Streams directly to the Disk...

Copied a 1 Hour Show (2.2 GB) onto a 8 GB Kingston DataTraveller and I
observed the same 10 Second "Wall" when playing from the USB Stick!!!

Does that suggest the HVR-1600 is Encoding MPEG2 Files which the
MediaMVP-HD is unable to Play past the first 10 Seconds??? If so that
could be a "Problem" since those are Hardware Encoders on the HVR-1600
Tuner Cards (one is a Model 1183 and one is a Model 1181) and I doubt
there is little or no Tweaking Possible???
