Re: possible sync issue with 1080i content @ 1080i
Interlaced modes play content the way you described when frame
speed is not exactly synced, mplayer for example determines playback
speed by evaluating responses from the audio driver. As a workaround
you may use the -speed option in mplayer, set it to a value a bit larger
or smaller than 1.00000, depending wether video swaps too fast or too
AFAIK, mplayer has no option to determine its playback speed by evaluating the Vertical Retrace Interrupt (not that I really know if
nvidia drivers are passing them to applications).
