This only works from the program guide as viewed from after watching 
TV.  It does not work when viewing the guide from the scheduleing menu.  
I had submitted a patch a while back that added an option to allow you 
to jump right to the guide when entering "Watch TV" so that you could 
just then parse the guide and hit M to go into TV assuming that most 
people just do that anyways since the chances are you're not going to 
just watch whatever the default or last channel tuned was.  Try looking 
back through the archives to see what was submitted.  As I recall it 
didn't get applied but it's out there against the pre-0.15 code.
