Both the USB tuner (pctv 290e) and HDHR connect are plugged into the master aerial amp/distribution hub.
Both tuners report very good signal.
Nonetheless from experience over the years (mythtv with PCI DVB tuner) I know that stream error are a fact of life... but that most players are resilient to an extent.
I guess I could script a stream fix on every recording, but this was never necessary recordings with the 290e tuner.
Also the way the recordings from HDHR "fail" is very consistent. There is no element of one working but not others.
I have recorded the same program on both tuners concurrently and can demonstrate the difference.
I was speculating that the problem could be in the way that the HDHR packetises the TS stream.

Network from the HDHR and RPi are both hardwired 100mbit ethernet into the same GbE switch. The ubuntu VM running my other tvh instance is connected via GbE from that same switch.
Pretty sure that the networking from the HDHR to both RPi and VM server is not to blame since watching live TV is working well - no glitches, artefacts etc

Agree - this is why I am moving to tvh on ubuntu on a xeon ESXi server

Thanks indeed for the offer.
I think I will try some more tests 1st.
Actually my RPi has dropped off the network recently and I didnt get round yet to check if its fatal :( hence my drive to get the HDHR solution working.
