Hi
I do hope that there is someone out there that can help me ..... I have just purchased 2 PMP from ebay and am having trouble getting video images onto the player that is pictured above ... (it has the software TV802 MLC V1.2.3A ... Hardware S308A V1.3) ... I am converting the videos using Prism Video Converter to .avi format, with the same sizing and kbps as the video that is already on the player.... I know that the videos work on the players, as they work on the other player that I purchased ... I am getting as far as downloading them to the player, however when I select the file on the player it gives the error message "FILE NOT EXIST" :evil:
please please please can someone help me as it is driving me nuts and having one child that can view videos on theirs and the other that cant is making me insane with the fighting and arguing
