http://forum.xda-developers.com – I got my IdeaTab S2109 for days. Get the high using experience on the tablet. Here I wanna start the topic how to get a smooth video playback on IdeaTab S2109. I note this tablet can only support a few standard formats like H.264, MPEG-4. I got some AVIs to S2109, but failed. Put and play AVI on Lenovo IdeaTab S2109 for smooth playback is the solution I found from google. Anyone here can share your tips or experience with us. (HowTos)
