AC3 audio, stuttering HD video, SVN r20459
#1
Just upgraded from 9.04.1 to SVN r20459 and have the following observations.

1. AC3 audio now works! Great news. I use both a analog audio connection to my TV and a digital connection to my receiver. With AC3 sound, I hear a clicking noise on the TV. Is it possible to either (1) disable the analog audio output when processing AC3 sound, or (2) convert to stereo output for the analog interface?

2. When playing a movie with AC3 that played well in 9.04.1 (Amadeus, media info below), the video appears to have problems -- a message at start of play that says "Failed to init video filters/scalers. Falling back to ..." and stuttering.

3. During playback the menu button stops play; it used to continue play but go back to the file list menu. Is this change design intent or a bug?

XBCM log at http://filebin.ca/jgrhwj ; media info for Amadeus below.
