In contrast to the older versions of Cdex, if you play back encoded files via DirectShow, rendering is via the Nero codec, not via the standard fraunhofer/microsoft layer 3 codec. This is a very strange behaviour, probably because there is something wrongin the file header or so.
in the attachment I show what the problem is,. The top half is a screenshot from Graphedit with 170 v4. DirectShow chooses the Nero codec. The bottom half shows how it is with earlier versions (1.70 v2). Here the proper codecs are chosen.
The Nero codec is far less reliable (at least in DirectShow). Anyhow, since this is strange behaviour, something must be wrong here
