Hi, I need to transport some SD tv footage to play on a flat screen TV using usb stick, Shop said mp4.

SD is 640x480 or is it 720x576 ?

I use AVS videoconverter and choose con to mp4 but dont see numbers that match those above.

I must not despoil the SD in the conversion, it must remain as if it was being fed to flat screen tv from a dvd disc or the original transmission.

Just what serttings should I be using ?

UK by the way.
