still dropping frames. The speed it drops depends on the content. This is all OTA. NBC and CBS are both dropping frames at high rates... but different rates depending on what is airing. Sometimes commercials don't drop frames, but the main show does. PBS is dropping frames slowly. ABC is not dropping frames. Fox is sometimes dropping frames. CW is slowly dropping frames. MyTV is dropping frames quickly. Fox5Plus is slowly dropping. iON not dropping. PBS is occasionally dropping.
I think this might not only be channel specific, but would have to do with the current show also. Playing my "Around the World in 80 Days" is a PBS recording and it is dropping a lot of frames.
All these frame drops do not happen when using the Default Video driver.
