[Closed] Any Adobe Premiere Elements users on here? Q about output?

Is there a way I can change the output frame size, for instance my original footage is 720x480 and I want to export a video at say 600x400 or smaller to reduce the file size for uploading to internet, but the best video output seems to be DVAVI, then if I set it to DVNTSC it stays at 720x480 and if I set it to DVPAL it goes to 720x576, and in both these settings the frame size is locked so it will only output at 720x480 or 720x576, is there any way I can change this? Or, any advice as for other settings welcome as it seems to be a minefield of settings and I've tried others which take ages to render only to fail or look pants so it's a lot of waiting or messing around just to see if something works. And will it make any difference if I used DVNTSC or DVPAL for playback on pc's or the net, I'd like to keep the original aspect ratio?? I've gone through other preset settings but they all seem to be locked??

What I've done so far is to output the video then take it to Windows Movie Maker to 'publish movie' with different settings to get smaller files, but that seems a bit long winded and thought there must be a way to do it straight from Premiere??
