downloaded movies ?!? what the difference ?!?

[FenDers]

Well, first off I am not asking for movies nor do I need any
but what I would like to know is that movies are posted on the net ( and that's all good and fine for some ) but there seems to be many different forms of these movies and I was wondering if anyone knew the difference between them

the four most common types are:

1 - screener
2 - telesync
3 - cam
4 - telecine

if you look on http://www.isonews.com it displays these headings under the vcd tab

have a look and hope you can help things like this really bug me !!

first of all.. don't get any other than screener, screener subbed, or telesync , and telesync subbed..

the others are ugh.. cam's are well crapy.. lol
most screeners are from vhs,svhs tapes
some are from bootleg dvd's..

subs are mostly from asia.. though.. some have german subs too heh..

telesync's are sometimes done with a sony cam in the theater lol but they looks so darn good .. nobody cares..

i have seen telecine.. they look as good as telesync's

cam's are mostly done on 8mm cams.. with all the talking and peoples heads shown in the movie argh lol

sometimes u get a real good cam.. well.. SOMETIMES.. haha
