ive done some video editing in the past, i have a copy of adobe premiere CS3, and a good computer. Ive done some editing in the past, but dont remember much

Ill be asking some questions that I hope you guys can answer.

First of all, im fairly certain my video camera saves files as an MPEG, but files are comming up listed as "movie clip"
how do i go about converting, i tried simply adding .mpeg or .wmv, no dice.
and they wont import into premiere.
thanks!
