MOD. file problem - Premiere doesn´t import audio

Hello.

I am trying to solve this problem but I can't find a way to do it, hopefully, you can.

I am trying to do an edit with some old videos from a Panasonic SDRH40, all videos in.MOD format.

When I play them on Quicktime or VLC I can hear the audio on the files, but as soon as I import them to Premiere Pro, a window pops up saying "There is been an unexpected error"... the funny thing is that this happens with only some of them, mostly the ones over 3 min. short ones work just fine.

I tried to change the preview file format and comp. linear on sequence settings and also use media encoder to transform those files in different formats with no luck at all.

I am using the latest version of Premiere on Mac.

Can Someone help me with this?

Thanks.
