have Canon XL-2 and GL-2; I video New York 9/11 Truth meetings (for free) and other things; hope to be using the cameras commercially in future

a couple of questions that I have are:

1)Why did Google discontinue the free video uploads? I know the free hosting service was too good to be true, and I'm sure they started to become overwhelmed, but who got to them to stop the videos that were telling the truth when the mainstream news-fakers would not?

2)The image quality on these New York 9/11 Truth video uploads on Google was initially superb. However, after about 6 months, one morning I looked at them and saw that the video images had s significant degradation in image quality (had become pixelated). Was this because of bandwidth considerations of Google?

3)I've used Sony Vegas Pro and Windows Movie Maker on my Windows computer but, with my new Linux computer, I'm very anxious to learn Kdenlive and Avidemux. However, I cannot get past the first step of capturing, and saving, the mini DV AVI files and have been banging my head (figuratively) into the wall over the past couple of days trying to figure this out. If anyone could help me, it would be appreciated. My telephone # is: (973) 743-1973.

Respectfully,
