How to map "missing" channels

Last Updated: Nov 02, 2012 04:03PM PDT
In some cases, broadcasters don't include the information that Simple.TV (and other DVRs) use to identify the station (and hence assign it a call-sign, logo and all the program information). These channels appear in the Simple.TV Settings windows as channel numbers such as "21.6" or "458.384" and have a little "gear" symbol next to them:

These channels can (generally) can be played back if you enable them, but you'll need to map the channel guide information to them manually. To do this, follow these steps:
  1. Go to Settings > Guide and take a look at the line-up.
  2. Open a new browser window and visit Type in your zip code and select your antenna or cable service from the drop-down menu.
  3. You'll see a list of channels, with various numbers and callsigns. This is a database of which channels map to which networks for your service.
  4. Look at the column called "Channel". This is the raw channel number and corresponds to the odd-looking numbers in the Settings window. For example, channel 20-3 in the silicon dust list would correspond to 20.3 in the Simple.TV list (they use dashes, we use periods).
  5. Look at the column called "Virtual Channel". This is the channel that is normally used by program guides and that would normally show up in Simple.TV.
  6. Now the tricky part. You need to go down the list of "Channels" on silicon dust's website and find which ones correspond to the channel numbers displayed in Simple.TV's Settings window. When you find one, click the little "gear" icon next to the channel and choose the correct virtual channel number from the list that's displayed (it looks like a little black tool tip with a list of channels inside it).
  7. Continue doing that for all the missing channels.
