I don't think they're all on the same frequency. I'm not 100% sure of the
terminology, but I ran scandvb and it locked on to about 6 local broadcast
channels. I'm fairly certain that they are different frequencies, but I
don't have the channels conf file in front of my to say for certain. How
likely is it that 6 channels from 3 different broadcast corps would be on the

I've tried and tried. I'm afraid it's going to break if I tear at the case
anymore. It's not mine and the vendor's Website doesn't list it for sale
UPDATE: Okay, one bloody fingernail later... it's open. I'll send pics when I
can get them. But right away I see:
1 NXP Chip: TDA 18271HDC2
1 Auvitek Chip: AU8522AA
1 Auvitek Chip: AU0828A

This is a problem with the install scripts, not with 2.6.27.
My distro has gzipped modules so the 'make install' command did not overwrite
the default mod.ko.gz. 'make rmmod' or whatever the specific make target is
in this project removes both the mod.ko files and the mod.ko.gz files. So,
uninstalling then installing works. Nothing to do with 2.6.27.
