How can i open a video i filmed with my digital camera?

i can't use winamp or media player because it doesn't allow me to see any images.

Try the VLC player - it can handle most formats.

What kind of video camera is it? Minidv? Minidvd? Harddrive? analog?
If you have a mini dv (cassette) camcorder鈥?
Your dv camcorder needs a firewire connection (ieee 1394) in order to download video, your PC probably did not come with a firewire port, so you will have to buy one and install it, since most computers (except possibly brand new) don't come with a firewire port, your camcorder did not come with a firewire cord so you have to purchase a cord too. Your camcorder did come with a USB cord and that is used for downloading stills from your camcorder. Make sure your camera is in playback mode.
The fine print in your manual makes reference to firewire (ieee 1394) connection.

If you have a mini dvd camcorder鈥?
You will have to finalize your dvd in the camera and then put the dvd in your computer's DVD burner (top loading only) and then you will have to convert the files (I downloaded handbrake file converter free) and import them into your editing program. Use the HELP feature in your editing program to learn about editing. Once you are ready to burn, your project will be burned to a different DVD and you can file the original away.

If you have an analog (VHS) camcorder鈥?br> You need an analog converter, either internal card or external such as the dazzle. It's very easy to use and come with good software. You would hook your analog VHS camera or VCR to the analog converter, the dazzle and then hook the dazzle to your PC. The dazzle cost around 70.00 , but worth the money if you have a lot of VHS to tapes to convert.

**Please Note There is no 8mm or Hi 8 to VHS Adapter that currently exsists. This type of VHS Adapter only exsists with VHS-C tape**

Try realplayer or quicktime. Depending on the type of file it is, it may or may not work. A lot of times I have to use quicktime to see my videos off my digital camera because of the file type.
