Based on the list, we threw an assortment of video files (including MKV) at the Samsung LE40B650, and – with the exception of DiVX AVI videos above 720p, and some 1080p Planet Earth rips in MKV format – most were played back successfully. We did notice some dropped frames when the bit-rate was very high, for example when we watched the WMV HD trailer of Alexander (incidentally we got no sound from this particular video as the LE40B650 returned an "Unsupported Audio Data" error).
