Ok, I added the options to my local.conf, rmmod hdpvr then modprobe 
hdpvr and checked the values by looking in /sys/module/hdpvr/parameters 
and they seem to have taken.  I then did another cat /dev/video0 > 
test.ts and this time it would capture for 17-20 seconds (I tried 
several times) before the blue LED would go out.  My backend has crappy 
Rage128 video, so I copied the files to my desktop, and they play fine, 
with audio.

I then unplugged the USB cable, turned the HDPVR off, plugged in the 
cable and turned it back on.  I see the following from dmesg which looks 
ok to me:

usb 1-1: new full speed USB device using uhci_hcd and address 46
usb 1-1: New USB device found, idVendor=2040, idProduct=4902
usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-1: Product: Hauppauge HD PVR
usb 1-1: Manufacturer: AMBA
usb 1-1: SerialNumber: 00A28B49
usb 1-1: configuration #1 chosen from 1 choice
hdpvr 1-1:1.0: untested firmware version 0x12, the driver might not work
hdpvr 1-1:1.0: device now attached to /dev/video0

I tried capturing with cat again, and again I got about 17 seconds of 
capture, then the bright blue light went out and the file stopped 
growing.  I dug around in the system log viewer and didn't see anything 
dmesg didn't give me. 

I then added the hdpvr_debug=1 to my local.conf and tried it again a 
couple of times, but I couldn't figure out which dmesg results were a 
product of which trials, so I rebooted the server.

Trying again, I got about 15 seconds of capture, and dmesg showed this:

hdpvr 1-1:1.0: config call request for value 0x700 returned 1
hdpvr 1-1:1.0: config call request for value 0x800 returned 1
hdpvr 1-1:1.0: transmit worker exited

That didn't look very useful, so I guessed maybe the hddvr_debug number 
had some control over how much debug was displayed, so I changed it to 
255 and rmmod and modprobed and tried again, got another 17 seconds of 
capture and dmesg had this:

(I don't know what came before this, the scrollback buffer didn't go 
back that far)

And that was it.  I'm not sure where to go or what to try from here.
