As title I have two questions basically, first off:

I find the 800 different conversion presets a huge annoyance and simply want Avi,Wmv,MP4 same quality, MP3 normal/optimal or what not, I don't need 50 presets for each device I don't have, so is there any quick way to remove all superfluous presets?

Secondly I have a Popcorn Hour which will only play wmv9 video so is there any way to edit the wmv preset to use wmv9 rather than the current wmv2?

Thanks in advance
