And other encoding. Some encoding have lag as it needs to read so far before it has enough information about the video or there's a bunch of video packets, then audio packets so it has to read a lot before it can start.
Remember you are diving into a well worn area (encoding, playback issues.)

I have sony bravia klv-32r402a. When I start the video after some time it lags for 1-2 second. I use micro sd card reader to watch movies. So is there any solution for its lag?
