[QUOTE="mm1352000, post: 886665, member: 82144"] Hello Yes I've seen this before - my opinion is that it is the codec. The complex and extended inter frame and inter block referencing that h.264 can use means that finding a "safe" entry point in the stream to start decoding from is not so straightforward. The first bunch of frames that the codec decodes may be missing backward-references from frames/blocks that the codec didn't get the opportunity to decode. Some streams are more affected than others, depending on the options that the broadcaster is using to encode the stream... mm [/QUOTE]
