DVR without guide info

I have a local channel from my HDHomeRun that has no guide data whatsoever. It is a local sports channel with replayed high school games. Is there any way that I could record this channel every Sunday from 1-4 pm without having a program in the guide?

Alternatively, is there a way to create my own local guide for that channel and fill in only that time slot?

Easiest way is to map some channel to use for guide data.
See this post Channels without guide data cannot be recorded - #3 by slampman
And read that whole thread for other ways.

I noticed the latest DVR Beta release I installed yesterday now gives channels without guide data 1 hour segments, so with that update you can record these channels now.
