configuring tvtime with my devices

I have a stock Oneiric install. No kernel mods, etc, short of what comes via Update Manager.

I have an AverMedia A188 card. That's a ATSC and PCIe dual tuner.

I have never been able to watch tv with any of the usual apps: mplayer, tvtime, xawtv.

Can someone tell me whether there are drivers for this or not? I look at the pages on the 'net about the saa7160 and lgtd 3304 and it looks as though there are drivers.

So, can someone give some help with configuring the tvtime config file. I have us-broadcast, but have no idea what other mods are needed.
