I tried MPlayer and it doesn't play the movies that i downloaded that the preinstalled media player had no problem playing before, and it won't play the movies i recorded on canon either. MPlayer sort of plays the movies I had before, but not the ones I took on my Canon...some sound from the Canon video, but that lasts about 3 secs. Any other suggestions? Since I'm clueless about formatting, should I format the SDHC card on my NIT, before I use it in Canon? Thanks in advance!!!!
