#73 AC3 with 5.1->1.0->5.1-change misses 5.1->1.0 message

[Stefan Pöschel]

I recorded a movie from television, which was broadcasted with an AC3 track in 5.1. During the movie there was a short (ca. 700ms) temporary change to 1.0. The DVBviewer log shows this change, like my selfmade HD demuxer does. But if I process the (untouched) ES with ProjectX, the change from 5.1 to 1.0 is missing in the log, only the change back to 5.1 appears.

Attached is a short part of the AC3, which consists of the mentioned mode change - the following log is from that short part:
