As well as hoster for cdg's I also have winamp running on my computer. Winamp will play mpeg videos in a detachable window pretty similar to the hoster window, this is what I use for my laserdisc collection that I have imported onto hard drive. You can open more than one instance of winamp so you can also have it running your mp3 collection all with seperate slide contolls for volume. You can use 1 sound card for all 3 on a laptop or install a second soundcard in a pc and assign winamp to use that. Not bad for a free programme
