I want to make vacation videos and youtube videos, best software?

First I would like to make videos of my dogs and vacations, I would like to use various types of media such as video and pictures from my digital camera and camcorder( Insignia NS-DV1080p)

Second I would like to make a highlight video of one of my favorite fighters; I have all of his fights on DVD and would also like to use YouTube clips, pictures, music, etc.

I downloaded the trial version of PowerDirector 8 and was sort of successful making a video of my dogs until I tried to clip video from my camcorder, and the program just crashed, apparently it doesn’t work when you try to clip 1080p videos, the files from my both my camera and video camera were .avi files, but it wouldn’t edit the .avi files recorded from my video camera.

Then I put in one of my DVDs to try to open files from that to make video and it opened stuff but nothing happened when I clicked on it in the media library.

I don’t know if since I am just testing the trial version it is faulty for me or if its my lack of knowledge on how to do these things, but what can I use that does it all? Uses various types of media to make videos, such as ripping from dvds, can clip video from my video camera, can use youtube videos, etc?

I’m new to this but would like to create stuff and found on websites everyone recommending PowerDirector 8, but I don’t want to purchase it if it won’t work with my video camera clips and won’t use DVD clips. Is it asking too much to want something that can do everything? Do I need to buy a Mac? Any suggestions on how I can make the type of videos I would like to make with various media would be greatly appreciated!
