How can I play .avi, .wmv, .mov videos on a standalone DVD player

What you are tring to do is a hacker project. You want your standalone DVD player to play some files that it normally doesn't, try to understand why it doesn't - Your DVD player is a mini computer in itself, it has a a processor, RAM and ROM kind of thing which has software which is capable of playing popuplar disc formats you report it to be playing. Its absolutely analogous to the thing like .. you have a software on your computer which can mp3 files and not some other format like ogg and whatever .. to be able to play such files you will obviously have to use a different software(download it install it and run it )

So for your standalone player to be able to playing other formats than it does .. you need to download a new software for you dvd player and install it on it !! simple ??

But you probably dont even know what OS it runs and what is its RAM and ROM size and MOST important you don't even know how to change its software !!! and thats what only hacker's or an electronics hobbyist can figure out. It's an embedded system man !!

So there you are ... let me tell you something else tooo .. there are some other standalone systems which r embedded systems and full comuters in themselves like XBox .

So Xbox have an OS and a certian amount of RAM, hard discs ,CDROM and a powerfull pocessor and you yes YOU can change its OS to GNU-Linux and run a full computer using a TV and your Xbox!!!

there much more info on the net
