Opera cannot directly access and play with WMP the links which work with mplayer.
WMP 7 (which says it cannot upgrade itself) cannot handle most of the radio station links.
At a site discussing what still works with Win98 I found Winamp 5.3.5 suggested and it installed and despite an occasional 'illegal operation' at other sites, it played several m3u and pls links at
http://www.internet-radio.com/stations/classicalSeems to be associated with Shoutcast. All stations available in four formats.
Neither WMP nor Winamp handle Realplayer format RAM, or FLA.
So far everything works. Ancient FM, Otto's Baroque (rather poor quality).
The 187 classical stations include Groove, classical Indian music (Ravinder Singh), and Rock Classics.
I had to cut the volume to one tenth at times. Amazing speakers.
Runs hot. I tried turning off the video (Fn-F3 to switch to CRT) and the sound stopped.
I can exit Opera and keep playing. And then save station to a playlist. Mission accomplished.
Thanks for all the helpful suggestions for getting mplayer to work but I think I would need to compile it for older hardware.
This laptop is really too slow to play videos.
