It would mean that no judder and studder on HD-quality. With VDPAU the problem still might be "50Hz vs 50.02Hz" -thing so you cannot get frame accurate display. With every 5 seconds you might have duplicated display of frame or dropped frame. This is not acceptable by my
I fully agree. The *only* way to overcome this is by synchronizing VGA video timing to DVB-stream clock.
I realized this for some ATI-Radeon and Intel-GMA hardware. Even the brandnew Intel D945GSEJT now is fully supported with VGA/SCART/DVI/HDMI output.
For further details see:

This gives exact 50Hz 1080p mode. But does your VGA-cards internal clock generator allow exactly 148.500MHz. If VGA can only generate f.ex 148.460MHz clock then you
with vga-sync-fields patch you always have *exactly* 50Hz since video clock frequency is dynamically controlled and corrected.
have 49.99Hz output signal. Also is pulse width divisable by 8 etc.
this restriction is no longer true for Intel 945Gxx hardware.
