back in the day 90% of my programs were compatible with both PAL and NTSC but every now and again you would strike some program or game that was one or the other. To get around this especially with the 2000 you could create a jumper atttached to a switch and switch between the two modes. I subsrcibed to ACAR magazine in Australia and There was an article in there on how to do it If I get time later today I will find the issue and where you can download it etc. I gather your in the US so it is interesting that yours is showing up PAL under Sysinfo. That I don't have an answer for unless there is a Jumper in place or not in place as the case maybe that we don't know about. From best I remember it actually says NTSC/PAL where the prongs are on the M/Board. Hope this helps a little.
