So if I watch tcm live the picture is fine. When I watch it on demand many films appear in a black box. Black on all four side sof the picture-hugely frustrating! It seems this happened before on demand-is it tcm or comacast that needs to fix this?
What type of television are you using to watch these movies?
I looks to me like you are using an old analog television. The cable channels are all digital signal now. Since the movies are all old and in 4:3 screen format that would be what is happening.
If you have a digital television use the tv remote to change the picture size. Does your remote have a button to change picture size?
thanks for replying to me! Well.. on other on demand itemss with other channels the sd on demand is full box- the hd is not. but the tcm seems in hd mode no matter which you pick-sd or hd! odd- and yes i have a older tv.
