Some people get so emotionally worked up about programs.
Realv10 works just fine for me, the installer is straightforward, a quick run through the prefs & it works just fine for real media files, much better than the Real plugins for Winamp. Here in Canada, CBC broadcasts the national news in high bandwidth streaming Real & the quality is awesome.
The fact is, right now its almost impossible to use only one media player, (unless you use JetAudio, Real, WinMedia, or worst of them all, Quicktime, whose files Real plays incidentally). I'll be as happy as anyone when Winamp can really play Real, WM9 & QT streams & DVDs with 5.1 but until then...just relax.
p.s. Taming Real: Read the installation steps carefully & cancel the registration, take a run through prefs, set it to display player only & turn off the message centre...Then go to \Program Files\Common Files\Real\Update_OB & rem *sched... & *message...You'll find your Real starts very quickly & runs stably.
