It's actually a more complicated question than you would guess. The simple answer is that NTSC MPEG1 is 352 x 240, and PAL MPEG1 is 352 x 288. Where it is slightly complicated is that computer monitors use square pixels and TVs don't. For example, a 4x3 aspect ratio television in England is drawing 625 lines, and one in the US is drawing 525 lines, both in the same amount of height. A lot of dividing and multiplying later, it's possible to prove that 320 x 240 is the same as 352 x 240 NTSC, and 352 x 288 PAL, once you take into account the number of lines and the non-square pixels on TV. So, MPEG1 should normally play at 320 x 240 on a computer. If you've made a 512 x 256 movie somehow with Cleaner, it could well be that it's a 352 x 240 MPEG1 with its display size set to 512 x 256. I would go back and experiment with Sorenson to directly make a 512 x 256 movie, but try different data rates, to see where the compromise between quality and processor demands is best for you. In general, higher data rates are more demanding.
