Just in case, have you cycled the power to the HVR-1950?

Since it has it's own power supply, you need to unplug the power
to the HVR-1950 and plug the power back in (after invoking
whatever Deity/Deities you choose) for the HVR-1950 to completely
reset itself.

If the HVR-1950 got into an unusual state, it may take a cold boot
for it to get out of it.

You are probably doing this already, but since I haven't seen
any emails stating it explicitly, I am bringing this up.
