[mythtv-users] Can't record analog from Hauppauge 2255

[David Parker]

I should have mentioned that this is on Debian Linux 8 (Jessie), 64-bit,
running a customized kernel due to the patch required to make the card
work.  I live in the US, and I have Time Warner Cable with a mix of analog
cable and QAM-256 digital channels.

Sorry for the omissions.
