Yes, more than one channel works.  I do see the module TDA18721 loaded along 
with a couple other.  Again, I'm not 100% sure that this is the woodbury, but 
it works.  I can scan channels, I've watched 4-5 stations.  It seems to 
kernel oops every once in a while on very static-y stations.

I just upgraded to 2.6.27 and it doesn't work anymore.  Modprobing au0828 does 
not load up any other modules like the tda18721 and does not create 
a /dev/dvb folder.  This is a problem with the latest hg tip of v4l-dvb.


dmesg from 2.6.27 (not working):

As per my other email (sabrent/auvitek unknown usb device) I'm not entirely 
sure of the brand name.  The Web store lists it as "sabrent".  lsusb says 
it's "syntek", but Windows and the device manager says it's an "auvitek".  
The box has literally no brand name.  The only "brand" looking things are 
just acronyms like NTSC and ATSC.  The windows .inf file for the driver is 
littered with the words "auvitek international", "copyright auvitek" and the 
like....

Although I didn't buy the device, the first brand name that I identified would 
be "auvitek".  Sabrent was only found after back tracking to the the retailer 
and seeing the product page.  I don't think that "Syntek" is the proper 
coporation for the usb vendor ID of 05e1.
