How can I play .MP4 files?

My N70 plays .MP4 files before but when I reprogram my phone(because of virus software), I cannot play .MP4 files anymore. Can somebody help me? thanks!

u've to format ur phone memory. first make backup up ur files (contacts, messages....) from pc suite. then to format,
Try the three buttons, green button/3/* (until you get it to work).
- Turn off PIN code requests.
- Charge the phone fully.
- Turn off the phone.
- Remove the memory card (not really needed, but do it to be on the safe side).
- Put the phone on a table (easier to press the keys then).
- Press the three keys and keep them securely down and do not release.
- While the keys are still down, turn the power on.
- Do not release the three keys until you see the prompt for the home city
