Winamp 5.34 (full)

Type:Player
Kup: Not needed

Description of issues:
Really impressive environment for playing media, but there seems to be a problem with AC3 sound - player is reading it as "Mono" althought AC3 filter is running at the background. When video finishes and you try to play another media the program sometimes freezes, mostly leading to restart. This error occurs always, and only while playing media in this player.

Type: Codec
Kup: Not Needed

Codec seems to miss registry entries needed to run correctly under windows 9x. After installation the files are present in system but codec cannot be called from tv capturing or video processing application.
