DV- Now added to program info.
Yes, I also noticed the DV- prefix for the channels that carry those programs.
CTV Winnipeg carries DV, and a few months ago for a few minutes one of the CSI series shows started with the descriptive video, then after a commercial came back without it.
I don't know whether that situation was caused by Bell or CTV, but I would suggest checking Alternate Audio in the menu guide and ensure it is on English or your language of choice.
Just a note; if you record a program with a Bell PVR, you can change the settings in the alternate audio to have it play back in the audio of your choice. Like the Fire channel, record it with music, then play it back with Alternate Audio selected, and you only have the sound of the crackling fire.
