PSP Wont Zoom

Im using CloneDVD Mobile its a great program but im watching movies on my psp, So when it makes a movie in widescreen and i cannot zoom i lose 1/2 the screen size. Other programs i have used dont do this, what am i doing wrong? i ave tried AVC and MP4 both wont zoom, im also running anydvd if that makes any difference

Ok i have found the problem, its the output Res, I need to output a Video thats 320 x 240 can this be changed in DVDclone Mobile?

mobile already uses 320x240 for full frame (and 368x208 for widescreen) movies in the PSP profile.
You can check it in the devices.ini file.
