Received an MID X5a for christmas, no other obvious manufacturer unless I perhaps unscrew it from the filofax style wallet it is in. System says:Model:MID;Firmware: 2.1-update1;Kernel Version:2.6.29 root@localhost @368; Build number MID 1.0; I was getting on well with it after an initial reset. Connected to my PC via USB and copied files etc. Video files played fine using Gallery with pic and sound (.mp4, avi and wmv from SD card, youtube fine as well). I even connected it to the TV via hdmi and had excellent simoultaneous play on TV and the tablet. Then I carry on trying other "normal" things as a learning curve (nothing advanced believe me!!), go back to the video and now yes they play but on the tablet I only have sound - no pic. If I connect to the TV I do have a pic on the TV but stll nothing to see on the tablet. I have tried all sorts but without success. Different players show exactly the same symptoms. Can anyone offer a suggested solution please to get the pic back on my tablet? Cheers.
