Why are some channels in B&W and stretched?

Why are some of the channels black and white and kinda stretched vertically?
Just wondering.

Which channels are you talking about?
The only thing I can think of is that you're watching a PAL broadcast.

 

[Mr Tony]

only b&w ones Ive seen are programs on Peoples Network, which are old b&w films

The Pansat 2500A does automatic conversion to/from PAL & NTSC. I think I've caught some PAL stations before, because while watching them I would see some frame rate glitch every second or so (and signal quality was just fine). PAL is 25 frames/sec, and NTSC is 30. Also, I remember the picture being cropped at the top and bottom...
