[pvrusb2] Only static, no channels found, hauppauge wintv-hvr-1950 on mythbuntu

[Bill Kristan]

Hello - I'm trying to get my wintv-hvr-1950 working on the most recent
Mythbuntu. I've confirmed that the hvr-1950 works (it's fine in Windows for
both analog and qam stations). I'm using firmware downloaded from
iseley.net(the firmware on the driver cd was 16 kb, and my kernel
can't use it yet).
The firmware is loaded, and devices are created (I have /dev/video0 and
/dev/dvb/adapter0... nodes), but all I get from /dev/video0 is static.
Channel scanning (in mythtv or with w_scan) never finds any stations (I've
tried both analog and digital, and neither works). Eventually I'd like both
analog and digital to work, but for the moment my priority is analog.

Relevant dmesg output is here:

I can see there's an error in the tda18271 lines, but I don't know what it
means. I think all the required modules are loading - lsmod |grep pvrusb2
shows:

I saw in one of Mike's replies to somebody with this device that it's
probably a problem with the tuner module, is that the best guess at this
point? I'm not sure what to do about that, other than wait for the next
release of Mythbuntu next month (it's supposed to use a 2.6.35 kernel, I
think), but is there a way I can try to fix this now? This is a brand new
install on a new computer, so I'm up for switching to a different distro if
that would help...does anyone know if this device works with the current
Mythdora or Linhes releases?

Thanks for the help,
Bill
