MXF Audio Problem

Hi,
Newbie to these great forums here.

I have shot some footage on a Panasonic P2 using as FS-100 hdd and
usually I shoot Quicktime and have no problems.
I accidentally left it on DVCPROHD and was left with some MXF files.
I haven't used them before and have some problems.

I have the video on ___w01.mxf and audio in l01, r01 etc. files.

I dragged the video into premiere and it works but with no audio and
premiere won't accept the audio.

I want to convert the footage to match my other footage, in particular I want to get all my footage actually into avid dnxhd codec.

Anyone know a solution to my problem?

Oh, BTW, im using a PC.
