I thought that I would mention to you that I can play local Real Media files without problems (ones that exist on my hard drives). This is true now, and has been since the early version 10 builds. I have a number of .ra, .rm, and .rmvb files all of which play fine from inside MC. So, if you were talking about playing local files, this problem is not true of everyone.
I now use Real Alternative as opposed to Real One on my system, so it is possible that it could be a conflict with a newer version of Real's software ... But, I did once use Real One, and it worked fine. (I would suggest you check out Real Alternative though, and get that spyware laden stuff off of your computer).
However, when using MC to play streaming files (if that is what you are referring to) I do have problems.
See this thread:
http://yabb.jriver.com/interact/index.php?board=3;action=display;threadid=20258In that case (both with Windows Media and Real files) I too get the dreaded "Select file to play" dialog.
I really wonder what is causing these problems, as it doesn't seem to be everyone. In fact, I am quite sure a number of people on this forum use MC to play streamed and local Windows Media and Real files all the time ... Hmmmm. ?
