I'm using an HVR-1600 for OTA ATSC and OTA NTSC in the US.

With MythTV you set up the analog side of the card as you would a
CX23415/6 based card (i.e. tell myth it's an ivtv PVR-xx0 MPEG encoder
card as the cx18 driver is extremely similar).  You set up the digital
side of the card as you would any other dvb device in MythTV.  You can
do simultaneous digital and analog capture (e.g. Picture in Picture).

The cx18 driver is beta quality.  The most annoying problems are:

1. The first analog capture after modprobe doesn't work right.  Stop
that capture and every subsequent one will be fine.

2. Mono audio only, at a fairly soft level.

3. I2C bus initialization problems which essentially make the card
useless for some people.

4. No working VBI support yet.
