CS3: New project preset for HD video gives 1440 but surely its 1920 ?

Hi,

dusting off Premiere Pro CS3 as after 2 days of hell I cant get DaVinciResolve to even add a photo to a timeline and make it 3 mins without crashing.

I launch PP CS3, select new project and select HDV, I think thats right as I see no other HD video options.

But its 1440 x 1080p 25fps...eh ???

I know TV HD to be 1920x1080, my still image is 1920 x 1080

How do I set up a new project for HD 1920x1080 in CS3 as this cannot be right at all.

PAL 25fps by the way.

I simply wish to make a 1920x1080 pixel size jpg, (or would it work with .tiff ?  DVT wont goes black)  last for 3 mins and save as .mpg  or will I need to make an .avi then convert that to .mpg  ?

How do I make it 3 mins ?

I also wonder, will in fact CS3 be able to edit .mpg files as the last time I used PP  it only liked .avi hence again why I am having to try and learn Resolve.

Cheers
