nuh ugh!An opinion, and one I would agree with - except you're putting it up against HTPC software, which JRMC cannot (nor will it ever) match. It just isn't what the software is about.
A more accurate comparison would be JRMC vs BSPlayer or JRMC vs WinAmp. Comparing it to MediaPortal and XBMC is like comparing apples and oranges. They're both fruit, but there the similarities end.
JRiver is mostest awsome program ever! It lays waste to all those cheap communist programs!
I did have Winamp at some point, but It couldnt do much- however I assume that this would be another program that has endless plugins available??
