It doesn't say Dolby stereo... only

Dolby digital (AC-3) 2.0

&

Stereo

Also, i'm using PAL, and video source is downloaded from limewire... originally a camera recording.
I can't understand it as all the reviews on bitzi are good for this particular vid and there are a lot of reviews/inputs with no reports of problems.
The video is pristine but the sound is inaudible!
I think I may give up on this one!
Also not sure what you mean by "leave interlaced at default"
Also transcoding quality settings are can be set to custom in which i can alter the bit rate which is in kb/s... i'm pretty sure the auto settings for this vid chose, long play - 3382kb/s.
wow, i'm confusing myself now!
