Small codec pack - what should I add?

I've written AIW Player Components Installer to make it easier for people to get and install codecs (sometimes its really hard chasing for filters and decoders on the net) so that they will have no problems with playback in AIW Player (check my sig, also there is a thread on this forum ). So far I added Direct VobSub, ffdshow, AC3filter, matroska and real media splitters. Please take note that I take no credit for this awesome dshow filters - credit the developers. These filters can also be autoinstalled on new systems if you make an autorun.inf file with AIW Player. I am wondering what other popular filters to add. Please note that I don't want to transform this codec pack in something like Nimo or Ace. Just a little utility to install decoders for playback (no encoders at this time). Download Page:

Feel free to include RadLight MPC & APE decoders ;)

Can you, please, provide some links to those decoders? Thank you.

Awesome! Only 50 and 100 kb. I will include them in the next release of AIW Player Components Installer. One question: both the .ax files can be registered under win9x and win2k/xp platform as well?
