Similarity stops scanning after a few songs

[Springdream]

OK, but sorry to say, the help does not explain why more than one decoder is used for MP3.
Shouldn't just one do?
Anyway in the meantime I reduced and changed a lot (see picture) and this seems to work without problems till now.

Why don't you recommend those or similar settings as default?
Otherwise so many problems occour and many users just feel Similarity is too faulty?!

We trying to set most universal set (we already disable DirectShow decoder by default), but some users installs codecs pack that contain too many unnecessary and problematic decoders. And sometimes some decoders have native problems (example QuickTime can't correctly decode stereo MP3, not joint-stereo like most, native stereo). We can't solve all problems, but we try cover as many supported formats as we can.
