I believe this thread has the solution you seek.
Lisa,
The thread you're referencing is not the same thing I'm talking about... its just about making a toolbar to aggregate static options (which, don't get me wrong, is a great benefit!) Rather than try to explain again what n.player does (if the picture of the n.player bar didn't do it justice), perhaps you might take a look at it - it's free (if I remember correctly) and quite "light". It's homepage is
http://www.samo.cz/nplayer/ .
I brought this topic up quite some time ago... and as NoCodeUK said about homemade toolbars:
Unfortunately this will not show any details of track time/elapsed etc. This i do not know how to do
And nor will it give you dynamic items. For example, n.player replaces the "play" icon (when nothing is playing) with both a "pause" and a "stop" icon when something is playing. And there are "hover" effects as well.
I know... this clearly falls under the heading of "eye candy", but it's also quite functional as well. And if "little" n.player can do it, I had thought it might be easy.
If JRiver isn't interested in adding this functionality, perhaps it's possible to write a plugin... I'd pay $5 for it :-)
