lately , i've been noticing the great amount of .mkv files for anime . i also saw .avi ones, but simply felt better whenever i played them [did a comparison of the two side by side on my comp]. anyway, I own a ZuneHD right now, and i know for sure it can't play .mkv files. i also read converters that tried to convert them to a playable format also did not work in success. so now I am on a search for a pmp that plays .mkv files . any suggestions ?
