Please do not always _assume_ that it is actually PAL or NTSC, since
PAL or NTSC defines colour encoding, but the most of the time the
usual frame rates are associated with the colour encoding. However
like I've stated before nvidia on their newer drivers output PAL on
60Hz (on the tv-out of the card), not even 59.94006Hz, or 50Hz like
PAL is supposed to be for interlaced. The older CRT TVs (interlaced
monitors) expect PAL to run 50Hz. You can confirm this with xvidtune.
