My father bought your product the Walkman MPEG4 play....but when we saw your product the trademark is DV MP4 Player made in China while the other one is Sony made in Japan...the one which is made in China has an defective because when we charge it on the said charging hours when we use it the machine is low battery. What can we do? I hope for immedietly action. Thanks and good day

i have mp4 player when i download songs, vedios and photos it show me format error pls how can i fix that problem. thaks

My dear friend your mp4 player will only accept video which is in AVI format and not WMV format. what u need to do is download an AVI convertor and then convert your WMV format video into AVI format and then download that AVI converted video file into your MP4 player.

did u find a salution for that problem!!!!i've got the same problem!!!pls help me!!!

HI ALL! I Just had the same problem and tried with all my might to solve it looking for forums on google...and after hours of trying I FOUND THE SOLUTION!! You dont need to format anything..all you need to do is just create a new folder!!!! let me explain : BEFORE YOU BEGIN: first of all convert the video from any format to .amv .This must be done using the software supplied or you can find the software from websites my version is 3.68 LETS START! :) 1. as soon as you plug the device, it is shown as a removable disk on 'my computer'.double click on this icon. 2. there should be a local folder called 'mp4' or something which holds all the files you are copying onto the mp4 player in this folder (here you should find also the sample files supplied with the mp4 player).. 3. when u access this folder create a folder within the 'mp4' folder (noted above) and name it my videos or something like that.when you're done double click the foler u just created and copy the video files in there. thats it!then go on the mp4 player go on 'movie' then click on the button which brings the menu up (lets name the button 'X').select the 'LOCAL FOLDER' option using the 'X' button, then choose the folder where u have the videos placed (i.e my videos in this example). as soon as u click the X button when u select the video it shows you the contents of the My Videos folder u created.THIS IS THE TRICK:when selecting a video to play dont select it with the 'PLAY/PAUSE' button to start playing a video but use the X button (- i.e the button you use to bring the menu up..mine is named MENU on ohers its called MODE..)when u click the X button on the video VOILAAA it plays!! :) hope it works for u as it worked for me (it worked on the 3 mp4 players i have :)!) cya guys!
