My Nokia N70 can record video clips in MP4 format, sadly, my Windows XP doesn't recognise the format.

I have Real Player, Windows Media and Quicktime installed, none seem to oblige. I've tried searching in Google, but no help there so far.

Does anyone have the answer. It would be very much appreciated.

Download VLC media player from here: http://www.videolan.org/vlc/

Quicktime should, if it doesn't then something is probably up with your install.

I had exactly the same problem, in my case caused by not doing the default install of any media player (to try and avoid them fighting each other for file associations).

If you've already got it, Quicktime works - but if you want to install it and haven't already watch out for the shovelware that is iTunes, although at least the "Quicktime without iTunes" link is easier to find now.

Thanks for the info and help, I'll give it a go. I didn't realise with my phone that when I changed the quality, I was also changing from Mp4, to Mp3 or MMS etc.
