Model 1200

It did not properly work in my system's USB 1.1 slots. It was unable to tune any channels and eventually caused my system to lock while doing the dvbscan for ATSC channels. Luckily unplugging it unlocked the system.

After plugging it into a USB 2.0 card on the same system, I successfully ran the dvbscan with no trouble.

3rd Model

I just (April 2nd 2010) purchased a WinTV-HVR-850 model 1200 through, and it appears to be a different version then the two listed. This one has a serial number of B1F5 and is not detected by Ubuntu Karmic or Lucid beta. I have yet to be able to get this model to work!

Yet Another?

I bought my HVR-850 model number 1200 on June 19, 2010 from Fry's and it is giving me an ID 2040:b140. Running dmsg just gives me "usb 1-3.4: new high speed USB device using ehci_hcd and address 13" and that's it.

Possibly Valuable Information

Pulled this out of the Windows driver disk my for my HVR-850 with device ID 2040:b140:

It would seem that the tuner is the TDA18271 and the demodulator is LG3305.
