Have you tried more than one storage device? External Hard Drive? Another SD card? If yes, then you'll need to do the following procedure at the link below.
I cannot record after I changed the Storage Device in my Stream+ (CM-7600 CM7600)
If you've only installed this one Storage Device, then you should see the following.
- Press Home button.
- Navigate down to Settings and select it.
- Navigate down to Storage and Reset and select it.
- Do you see your Storage Device in this screen? If you do see your Storage Device on that screen, select it.
- Navigate to 'Eject' and select it.
- You'll see a screen 'Eject Device Storage. Your choices are Cancel or Eject. Choose Eject.
- You should see a screen '[your storage device name] Storage Device removed'. Then a quick message '... Storage Device is safely ejected'. Select OK.
- Now in 'Storage and Reset' category in the menu should also say '... Storage Device is safely ejected'.
- Now press 'Home' and then 'Guide' and watch a TV program.
- Install your Storage Device. Within a few seconds you will briefly see a message, 'storage device reconnected'.
- Press OK while watching a live TV program and now you should see "Play Controls" just above 'Channels'.
