winegstreamer error: decodebin0: Your GStreamer installation is missing a plug-in. winegstreamer error: decodebin0: ../gst/playback/gstdecodebin2.c(4701): gst_decode_bin_expose (): /GstBin:bin0/GstDecodeBin:decodebin0: no suitable plugins found: Missing decoder: MPEG-1 System Stream (video/mpeg, systemstream=(boolean)true, mpegversion=(int)1)
Install that first.
Though, arguably, wine should fail more gracefully here.
