I used Ubuntu 11.04 i386 to create an audio OGG file from FLAC file (SoundConverter 1.4.4). And I am really disappointed with the result. And I don't know where is a problem.

1) When I play file with ogg123 (1.4.0), it is OK
2) When I play file with GNOME TOTEM player (2.32.0), it is OK
3) When I play file with VLC (1.1.9) under Ubuntu, sound is corrupted
4) When I play file with VLC under WinXP, I observe gaps in music
5) When I open file with Audacity (1.3.13beta), I hear real problem, sometimes music even oscillates between channels
6) I see warnings about discontinuity in the stream from ogginfo (1.4.0):

$ ogginfo 09_-_Don_t_Stop.ogg 
Processing file "09_-_Don_t_Stop.ogg"...

It seems to me like encoded schema changed and older players cannot play new format correctly. This is not good...
