On firmware 4.0 x32 and I encoded some movies to put on my card but now the media player will not boot. I tried deleting my media to see if it was corrupted but that doesnt seem to be the case... I dont know what is wrong, is it the firmware? I tried reinstalling it. I'm using a Kingston 4GB JP microSDHC and the media player worked before but I dont remember if it was on or before v4 firmware.
