If it's going slow it might be your computer, what RAM, and CPU have you got?

i want use hdv for the better quality thats why i bought the camera but when i capture it using sony vegas 6 it captures as an m2t. file and is large and ive heard of programs that converts it. its too slow on the time line for editing, it plays normally in widows media player but is distorted, like a bunch of lines going up and down.

You might want to check out www.dvxuser.com as i dont know anything about vegas and you might be able to find someone there who also has the same camera as you.

how come a movie file is around 500 mb which use the really good cameras, but on sd or hd a whole movie would be around 40 gb?

Sorry im a little confused what you are talking about?
What cameras are you refering to when you say "really good cameras"?

You seem a little confused so I hope this clears a few things up.
Cameras they use for "The Matrix" and other films as such are actually film cameras, the camera takes shots of 24frames a second to physical piece of plastic (film). This in fact is the highest quality you can get, its even better then HD.
What happens next is the film is converted to a digital signal using a kine/telecine technique.
There are a number of signals this film can be converted to, lets for example convert it to the D5 digital signal, because this is the level where the best colour correction will take place (if they were to instantly convert it to the DVD MPEG2 signal, when they edit/colour correct the footage its quality will be shocking).
The D5 signal is an uncompressed digital signal which stores the video on three separate channels which are known as YUV or RGB, this takes up about 33MB a second so 1.98GB per min. The mini DV signal takes up 3.6MB a second so that's like 9.5 times less quality? Then when you go to DVD MPEG2 quality it’s around 20 times less quality of DV.
After editing and colour correcting the film, they then convert it to DVD which can hold around 9GB using "compression CODECS".
When you talk about all your files being different sizes this is because the video and/or audio is compressed with one of the many CODEC's out there, weather it is a HD, proHD, HDV, DV or DVD file, these is always compression in them.
I'll leave it there, if you’re still unsure about something give me as much detail as possible about your confusion so I can answer it accurately as there are soo many variables.
