i want to burn some videos to dvd to play on a dvd player. alot of dvd-r's later i found out that the vids cant be 4.7gb (or alot under the ones i wanted was about 200mb) and play on a dvd player it has lots of suff to make it play. i was wondering if there was a way to find out how much stuff i can fit on to a dvd-r with out just trial and error and alot of £ later. the vids are .wmv do other formats fit better? or other burners fit more on?
