Once upon a time, the only way to play RealMedia files was to
download the free or pay RealPlayer and install it. This wouldn’t
have been so bad if RealNetworks hadn’t made such a fuss about
selling you a more capable version or constantly reinserting itself
into the boot chain and system tray. Even worse, at one point the
RealPlayer proved vulnerable to files that would open your browser
and send you to a Web site–and exceedingly dangerous behavior.
All of this proved too much for too many users, and the
RealMedia codecs have slipped mightily in popularity. That said,
you still run across the occasional .rm or .ra file–and if you
want to play them in your browser or WMP and many other popular
media players without installing the Real Player, you’ll want the
Real Alternative codec.
I’ve been using Real Alternative for years. It works well and is
100% transparent–that is, it doesn’t bug you about anything, ever.
It just registers itself as a DirectShow filter (Microsoft-speak
for a codec) and with your browsers, then decodes virtually any
Real Media file ever created. It’s good enough that I haven’t even
considered installing RealPlayer in years.
