Ive taken a DivX .avi film at 23.976 fps and got it to playback in my standalone after re-encoding with CCE and using pulldown.exe
All well & good there. Now, as I understand, the pulldown stage raises 29.97fps flags, thus giving it NTSC status, and sure enough, mmy standalone actually says NTSC when playing back. NTSC resolution is 720x480 right? My original .avi was 576x240, and using several methods and programs, the resized resolution ought to be 720x300. Ive added borders (90 pixels on top & bottom) with avisynth to conform to the 480 height, but on playing back the film on my 4:3 television screen, the picture is vertically stretched unless I hit the Widescreen Button on the remote, and even then the picture looks as though it ought to be 310 pixels rather than 300.

I could easily resize the picture to 720x576 and add borders top & bottom, and it would look perfect. But 720x576 is PAL, surely??

Im going round and round in circles at the moment, and I dont seem to be making too much progress. Could someone please point out the (Im sure) blindingly obvious facts as to why my resolution looks all wrong.
Thanks.

Think I worked it out. NTSC on a 4:3 screen looks like 640x480. I adjusted my picture size to 720x266 and it looks awesome!
Correct me if Im wrong.

You are perfectly right. If you use this formula in Excel: 720/540*240/11*10 you will get some 272.72 Make it 272 and avoid 266 since it is not a multipel of 16.
