This patch (9.0.1531.0) makes most problem disappear, DivX works fine now,
but...
The new DivX version V7 produces standard also MKV (H.264/AAC) videos and the used suffix .mkv is not recognized by the ,for the rest very good working!, PowerDVD_1531.
This must be a very little patch to correct, because a simple rename to a filename with .DivX as the suffix made that the testfile could be played with PowerDVD.
Thanks a lot for the fine patch!
