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 |

idk, maybe one stream is a foreign language, or for commentary. something like that.

case 1: it is a prosumer camcorder; check the specific manual <- unlikely
case 2: it is a downloaded file; ask your source general: it appears as if avchd does support mutiple audio track that can be encoded with dolby digital (hence your shiny dolby logo) or pcm (and possibly something else). probably worth reading: a. about avchd in general http://en.wikipedia.org/wiki/AVCHD b. about the container itself http://en.wikipedia.org/wiki/.m2ts#Formats This post has been edited by smok3: Apr 29 2012, 13:22 -------------------- PANIC: CPU 1: Cache Error (unrecoverable - dcache data) Eframe = 0x90000000208cf3b8
