What is Type 2 Avi?

[Mgefen]

When I import a clip which been caputred from Canon S1 IS, it shows me an error: "Unsupported compression in file"
The end of clips from the Canon S1 IS is "*.avi"
I used "help" - and i found this:

"Video formats:

Type 2 AVI, MOV, MPEG/MPE/MPG, Open DML, and WMV

Note: Type 1 AVI clips must be rendered before they can be previewed from your DV device. To render a Type 1 AVI clip, add it to a sequence in a DV project, and build a preview file of that section of the timeline."

My question is:
A) How can I now what type of avi my clips are?
B) In which program I can change the format of my clips to those which Premiere requests? (Type 2 AVI, MOV, MPEG/MPE/MPG, Open DML, and WMV)
