Please, do a cvs update before doing your patch, in 10 days

Please create a new file asf_mmst_streaming.c and put all your 
related code in it. I should rename asf_streaming.c by asf_http_streaming.c
and have the asf_streaming.c contains only the asf_streaming_start and the
shared functions with all the protocols(if there is any!)...
It's simplier for me than to try to see what you changed in asf_streaming.c
For example don't comment out the line 66:
                !strncasecmp( proto_s, "mms", 3)  ||
even if you try mms first. The reason is if someone is behind a proxy or what
ever gateway/firewall the mms protocol can be block and the mmst will failed
so we have to fall back into using http, it's why this line is there.
BTW, have you read the comment just before the asf_streaming_start 
function? It explains the same this that I just wrote.
You should only have to uncomment the line 61 in asf_streaming.c to make
your tests.

For what I recall the asf header is not saved.
For ASF/HTTP, you don't need to open a new connection, 
for seeking, you just send a new HTTP request in the current connection.
I don't know about mmst.
You also need to clear the cache after you received a possitive answer from
the server.

Please redo your patch with the above changes, and I will give it a try,
thanks.
