If you have program guide associated with the channel, then the only way to set recording is to select the program in the guide and click Record button (in standard view). Without guide data associated with the channel, you can select the channel and click Record button, and then specify any time frame. When there is guide data, that has a single program that runs from 7 AM to 7 PM, you do the following:
1. select the program in standard view (Olympics, 7 AM - 7 PM) and click Record.
2. select Record (record only this program), and click Next.
3. In "Start recording early by" box, enter -299 minutes (negative value); and in "Keep recording after program ends by" box enter -119 minutes.
4. click Finish.
This will start recording at 11:59 AM, and end recording at 5:01 PM (instead of 7:00 AM to 7:00 PM). The negative numbers let you do the opposite of what those parameters are supposed to do.
