Except for WMV9, those are just container formats, not codecs. They can be encoded using Xvid, H.264, or any number of other codecs. Mp4s encoded with Xvid are playing fine on her phone, but not when encoded with the h.264 codec. My understanding is the Wildfire S supports both of these, among others.
