I've found that after I upgraded my PowerMac 6500 from Mac OS 8.5 to 8.6, the Apple Video Player application doesn't work right. I usually see the TV input momentarily every time I change the channel, and then the video window goes black. To get the TV input back, I have to change the size of the video window. It's quite a pain to change the window size every time I change the channel! Any ideas?
Also- I have the latest version of Apple Video Player.
