Could you try the following: http://www.winehq.org/wineconf/stream.html and tell me how it goes?
Well, the mdk RPMs of mplayer don't support rtsp, and I don't think I'll have time to rebuild before wineconf (Have to help my sister with javascript, se has a uni exam in a few days), and quicktime gets a nice "Connection failed" error after switching transport various times. BTW I have 2 firewalls, one behind the other, filtering everything and anything that's incoming, and I don't really want to change that. Maybe you could provide a trial version of crossover <Whatever version is ok to see the stream here>, or let me know what day/month/year wine was OK, so I can get that version from CVS.
Ivan. p.s. Just tried again and quicktime just switches transport for ever until I close it.
