So this means the DirectShow filters are only useful for playing local Vorbis
files now?
I?m sure I use to use these filters about 5 or 6 years ago with Oddcast encoded
streams with no problems. I take it this functionality was removed for some
good reason?

Hi Ross,
I just did a quick test using Windows 7 and it played one song, afterwards
it stopped. Does stationplaylist use chained Vorbis?
Chained Vorbis is unsupported by the DirectShow filters.
I have tested the above link using Mozilla Firefox 3.6.10 and the result
was the same, only one song was played.
Cheers,
Cristian.

To add to my last message, surely WMP should also at least play to the end of
the song, but it won?t even start.

I will add a check into OpenCodecs installer for this situation. A quick fix would involve editing the following registry key: HKEY_CLASSES_ROOT\Media Type\{e436eb83-524f-11ce-9f53-0020af0ba770}\{49952F4C-3EDC-4A9B-8906-1DE02A3D4BC2} and deleting the value "0,4,,4f676753", which for me was mapped on "6".

I’m using a Windows development component which uses vorbis.dll, ogg.dll, vorbisenc.dll for encoding an Ogg Vorbis file. It's all working well except for one user occasionally has a 1 hour file appear as 2 hours and it plays at half speed. It is being converted from stereo to mono before feeding the encoder with a channels=1 configuration. Here is an example file which will be available for a few weeks. http://stationplaylist.com/temp2398/Hour2.ogg Any ideas why this should occur sometimes but works fine other times? Ross.
