About jerky playback under Vista and Evr I've tried to switch Aero ON. it was off because I've always got jerk playback /stuttering (with or without reclock is not related).
I've two monitor . the pc monitor on dvi-vga , a 19" Asus 1440x900 75HZ. the plasma panasonic 37" connected via hdmi dongle (on yellow dvi port) the monitors are in extend desktop mode.
Tried with an mvk 720p 25 fps (so the monitors refresh match both). MP on the plasma (the secondary) I got random stuttering / jerky play. I switch the plasma as first monitor . the problems gone. work fine. I've 8.8 catalyst. this is a big issue because the tv can't be the main monitor.
I've tried MPC-HC on 2^ monitor seems work fine (evr and same filtergraph).
Is it possibile that issue is MP related?
