Having read through the forum, there are obviously some issues with MPEG4/H264, but this one seems strange to me. Would appreciate any help. I have two files that seem pretty close to identical from a technical point of view but first one plays ok (slight audio problem, dropping every 10sec or so but watchable) and the second one which gets a “This file is not supported” message? Media info below…
