NTSC video - PAL conversion again

So, just a little question. If all this stuff is always true, why when I see my Divx on my TV I see it in perfect condition? No artifacts.

Well, phosphor used in TV's and monitors has pretty short time of emission, so I can say just that it is very barely visible, maybe if just hardly want to see. Xeesdeni: how longer is usually doublerated DivX video from singlerated - in percents ?

I have PAL system in Argentina and after trying, I didn't see anything.

Uh,uh... scmccarthy, I don't know whether you express yourself bad or your picture is wrong. Analog TV can't grab whole picture (frame). It displays what coming in interlaced way. If you put twice same picture it will practically display it at half vertical res. - so work old home computers as Commodore 64 and similar with TV out. Increasing vertical resolution, and sending interlaced will produce too much flicker, therefore old computers had usually vertical res. of 200 lines. Digital TV's are different story, and can do lot of things, this is not relevant here. Btw. by bigscreen TV's I don't like that horizontal lines are always too visible, even by static scenes.
