I watch digital TV over-the-air and I've scanned for my channels, but I'm still not getting WGBH. Can you help?
Why has my over-the-air TV reception recently changed or become worse?
How can I find a list of WGBH's TV channels?
Why does the background music in some of your programs overpower the actors speaking?
Why do I hear an extra voice describing things that happen on the programs? How do I make it stop?
