Summary: Reduced bitrates on some mms streams

Initial Comment:
When listening to the following stream:
mms://union.surrey.ac.uk/GU2Live
on Windows (with Media Player 9), I get a bitrate of
over 100kb/s, and it proudly proclaims the stream is
'Optimized for Media Player 9'.

Playing the same stream on Xine (1.0), I get a bitrate
of 21kb/s. I have the latest (2005-01-15) 'essential'
Win32 codecs installed.

I have tried this on several machines (Windows and
Linux) and the result is always the same.

yes. It is 1.5 Mbps.

I think the problem is that xine does not detect all 8
streams in the link mms://wmedia.siol.net/tvpika/live (4
audio and 4 video) but rather defaults to the 4th and 8th
streams. Here is the relevant output from verbose=2 option:

Guessing here, but I'll reply anyway.

Is your 'Network Bandwidth' setting in the 'Media' section OK?

I have the same problem with these mms protocols that supply
multiple bitrate streams (uses asf format):

mms://wmedia.siol.net/tvpika/live
mms://82.145.212.24/ktv3

 I tried the suggestion and changed the MMS Protocol to TCP
instead of auto and the problem is not solved. xine, totem,
kaffeine and mplayer always chooses the last stream which is
not the highest bitrate supported by my connection.

Any suggestions?

Apologies.

I found the 'MMS Protocol' option in the configuration, and
set it to 'TCP' instead of 'Auto'. The stream works fine at
the higher bitrate now.

Should the higher bitrate stream not be the default when
'Auto' is chosen, or is this something that is set up at the
media server?
