Hi Devin,
I'm the person that has joined yesterday night on IRC channel to talk 
with you about this post.

During July, I've already talked with you about a problem 
(http://www.mail-archive.com/linux-media@vger.kernel.org/msg07728.html), 
but I was new and not very able to do debug and explain the problem with 
good test case.
After two months of tests and 3 adapters used (Hauppauge Nova-T, a china 
generic Intel CE9500B1 and Pinnable Hybrid Stick 320E 
EEPROM-ID=0x9567eb1a, EEPROM-hash=0xb8846b20 - only this one don't 
work), I've more information for you.

My configuration is very similar to Miroslav, Fedora 11 with kernel 
2.6.30.5-43.fc11.i686.PAE; v4l-dvb tree downloaded yesterday 
(15/09/2009) and I use scandvb to scan the channels. I've tryed your 
repository too, em28xx-vbi3, but it seems the same. The driver compile 
without problem, the system is rebooted every time I recompile it, 
modules are inserted without options and dmesg doesn't show any errors 
(http://pastebin.com/f340bf982).

Now the problem, very similar to Miroslav if MUX transmit only one 
channel; during tuning, the DVB-T stop on first MUX tuned and all MUX 
found after this one are not tuned and channels are not recognized.
During tests, I've seen that if I change the MUX order in input file for 
scandvb, I can get channels list tuned from first MUX... after more 
tuning sessions to compile the list, the problem persist during normal 
view of transmission...

If you need more info ask to me, I'll be very happy to help you; if for 
you is useful, I've saved a tuning session with usbsnoop from windows 
and I've not done this for linux, but if you need it I can do (I need 
some time to do this because I don't know where to start).

Thanks for your support,
Sebastian
