Because the video streams contains the Aspect Ratio information that 
informs the player
how to rescale the image (16:9 on a 720x576 results in 1024x576).
I'm not sure where the problem with your -vo mpegpes is; can you please try

mplayer -noaspect -vo mpegpes -ao mpegpes dvbfile.ts

and tell me if the card plays it?

Thanks.
