How do I start? I want to make a movie using photos, small pieces of films and a soundtrack

no feet in 8mm
roughly 8mm is 1/3 of an inch or 3/8 "

On the remote will be either a button marked "status" "display" or "sound mode". Push that when the DVD is playing. If you see "1 English" or "2 English" or even "commentary" in the OSD. Then you have found the way to change the soundtrack. Pressing the up, down, or sideways arrow keys should take you to the place of the "1 English" etc and highlight it. You should then be able scroll to one that turns off the commentary off. For example 1 English might meant just the normal soundtrack in English, 2 English might add subtitles. If the film has other languages these will also appear. Some might have Dolby soundtracks and other modes so if you want these make certain you select them.
Sorry I can't be precise as to which button to press as you didn't state make or model number.

I assume you haven't put a reel of film onto the projector and looped it through to the back spool. The front spool usually 'freewheels' whilst the film is pulled through the projector and taken up by the motor driven rear spool.
It is possible that the friction drive and/or drive belt have deteriorated with age, as the mentioned projector is a rather elderly 'classic' of the dual 8mm series.
If in doubt, don't risk your family pictures. Try the unit with an old piece of film on small spools.

Here is the soundtrack listing on the films website.

I know this post is old but I found a solution. The axle going to the sprocket is locked up with something sticky. You have take out the two screws holding the white plastic piece around the sprocket. Then loosen the small bolt on the big wheel on the other side. Remove the big wheel. Try to push the axle through to the other side. If it doesn't budge easily, hammer it out. That's what I had to do. Then clean it up real good with solvent, like alcohol. Lube it with grease and put it all back together. Worked for me.

Use the "Windows Movie Maker" software to merge audio and video into a movie.
It's included with Windows XP.

i think you can try another kind of movie downloader.
have a look from http://free-download-films.com/]
it contains much information about film.
hope it can help you more or less!

Sorry, but the ViviCam 5385 does not record any sound when in video mode. You can add a soundtrack using video-editing software on a computer, but you cannot record one on the camera.
