hi, i've recently gotten this real media file of a show i like, which when i play is in 2 different dubs, how would i disable one of the audio tracks ? cause its irritating watching a show when there are 2 different language dubs playing at the same time.

Media Player Classic along with Real Alternative will allow you to toggle between audio channels.
Assuming it is a real media file of course. Surprised Real player doesn't work.
