right. but from my experience recent dedicated hardware deinterlacers
mostly produce better results than their software (PC based) competitors.

right. The original purpose of my patch was to establish a basis to
synchronize VGA video timing with an external signal source (e.g. a DVB
stream). Otherwise you always will have more or less jerky playback.
The capability to produce fully synchronized interlaced RGB output on a VGA
port is only a pleasant by-product of this.
