No clue, it works for me... (Or at least, did last I tried it). I was thinking
perhaps an error in your config somewhere, but if you're using the downloaded
config w/o any changes, that doesn't seem like a possibility. I'll be poking
at this shortly (later today, I hope), with an HVR-1950, will see what I can
see then...
