I sent the response directly to Nathan, but this is a FYI for mailing list/

The Hauppauge WinTV PVR 250 (and 350) does not use the BT878, the
card uses an integrated hardware MPEG Codec "CX23415" from
Conexant Systems, Inc.

Conexant Systems, Inc is the company owns the Brooktree video
BT8x8 line. According to the web page below, they do not release
any information on their chipset without a NDA, and $10,000.

There is no FreeBSD driver, but there is a Linux driver and a web site
that documents some of the registers is at:

The web site says the YUV information can also be obtained, but is packed
in a non-standard way - no mention how it is stored.
