This was one of the last visual things bugging me with the driver. The screen always appeared vertically offset by 10-15 pixels from the broadcast video. According to the cx25840 documentation, VBLANK should be 22 for NTSC and 34 for PAL/SECAM. This patch sets it to 22 or 34 depending on the card region (although I can only test NTSC). It was originally set to 36 so probably NTSC people will be the only ones to notice any big difference.
