Cannon Powershot Digital Cameras
How can you resize home made videos from a Cannon Powershot SD900 digital camera?
I made alot of videos that i want to upload on youtuve and myspace video, but they said that the file is too large 
Is there some program I can download to resize it?
I don’t know about file limits of MySpace Video, but with YouTube, you are allowed files of up to 1GB (or 10 minutes) in size. That would be roughly 8 minutes of high quality movies taken with your Canon.
So, if your movies are less than 1GB in total size (or only a few minutes long) then you should easily be able to upload them.
But, generally it’s easier in upload times if you compress your movies.
You can use Windows MovieMaker (which is included in XP). You can tell the program how much you want to compress (or what size) you want to make your movies. It’s also a good idea to edit your movies (to cut any useless or unnecessary bits out). You can even add a soundtrack etc…
Cannon Powershot Digital Cameras
are cannon sx100 powershot digital cameras easy to use?
Absolutely, but the SX110is is now out so you should get that one instead. You’ll get a few extra refinements including a big 3 inch screen. One of the “easiest” things about this camera is the use of AA batteries. Like any P&S camera, it has a full-auto mode so you don’t have to do any thinking.
