I've contacted my TV tuner's maker and it's impossible to disable it. Thus, I either have to get another TV tuner, find a program that doesn't have audio-video synchronization problems (pretty much everything I've tried does), or find a way to extract the contents in overlay so I can use them. That is, if I can take a screenshot with PrtScr and I get an actual image instead of the color 16, 0, 16, then that will work just fine. Adobe Flash Media Live Encoder is the last resort, but I can't get it to pick up my TV tuner's audio stream. I get the video just fine, just no audio.
