It's working great here on my S9. Don't know why???? TV system set to 1080i 60. Aspect: Auto, Video out: YUV, Digital Audio out: LCPM Out. Feeding the composite video to a Modulator on an open channel for feeding multiple TV's. No stuttering, freezing or A/V sync problems noted anywhere. I wonder if some problems might be caused by TV System being set to 50 (European). My newer TV's will lock onto the video if the STB is set to 50,{???} the old analogs will not. Don't presently have a digital(HDMI) television available to hookup directly. I've also set the clock using GMT Usage: Off. It's still right on after 5 days and a few timer and manual recordings. Going into its quasi-standby mode more than once, via remote power button or after timer operations. This is puzzling, why it works so well for me, and not others. Could it be mine is from one of the original early batches to land on these shores???? Don't know how that, no, any and all of this's going to be answered.
