Update from last night:

Rechecked Mplayer, and made sure that it's using Alsa. I'd previously messed
with the Alsa config options on Mplayer, but I've now left them as default,
and can use Mplayer at the same time as Mhwaveedit (which uses Alsa) is
playing an .ogg file. So far so good.

Opening Firefox, and starting the live audio stream from RTL runs fine, but
now Mhwaveedit tells me that the cards busy.

Back into /etc/mplayerplugin.conf. I'd added the line:
ao=alsa #added by me
This was obviously wrong as the comment was on the same line, so I changed
this to:

Now I can play a live audio stream from RTL using, at the same time as playing an .ogg file through

Incidentally. When I could not play both at once, ps auxw showed 2 instances
of Mplayer, but no mention of Alsa. Since I added the "ao=alsa" line
to /etc/mplayerplugin.conf, I now have in ps auxw, 3 instances of Mplayer,
and all displaying "-ao alsa".

I'm about to look at FFMPEG, which I don't have installed on FC2.

Thanks for your help.
