Default i have a video that has 2 audio streams..what does that mean?

i have an AVCHD video..then using media-info. i found out that it has 2 audio streams..first and second audio streams both say "224 kbps, 48. kHz, 16 bits, 2 channels, AC-3'..now what does 2 audio streams do with my video?

and when i play it with windows media player, the dolby digital plus logo appears in the lower left corner..again what does that mean? just a newbie..please bear with me..thank you

If you play the video in full screen mode in Windows Media Player, right click on the main playback area and select "audio and language tracks" - there, you should be able to select one of the two audio tracks. So have a listen and see what's it all about (maybe one is a commentary track?)

Not sure about the Dolby Digital Plus logo, doesn't look like the soundtrack in the video is in this format (if it's AC3, then it's just plain Dolby Digital, no 'Plus'), so it could be that the video was simply encoded with the watermark in place for some reason.
