FLV audio increasing on import

Hey guys,

I'm importing FLV files into Captivate 7, and I'm noticing an increase in volume when I import them into the course. However, the regular MP3 files throughout the course remain the same volume. Outside of the course, all audio is from the same batch and IS definitely the same volume, but the FLV audio is changing on import.

Anyone else have this problem? and know how to fix it in Captivate?

Thanks in advance
