96k tbn vs 24k tbn
I've got a Panasonic GW20 with serviio 0.5.2. I am using the transcoding profile posted in the 10-page thread. I've got a few mp4's here, filled with AAC / h264. Interestingly, most work, except for a few. The only difference as far as I can tell from running them through ffmpeg manually was 96k tbn vs 24k tbn. Whatever that means, the documentation on ffmpeg is a bit sparse on that. Ideally, I'd like some help in the next ten seconds, as I'm now unable to watch episode 8 and there was a huge cliff hanger at the end of Episode 7. But ah well 
The file plays with audio, in sync, but I cannot forward or reserve without it crashing (a minor nuisance), but more importantly: The picture breaks up into square-shaped artifacts every time the picture changes rapidly, and still moments feel very blurry (probably also artifacts), and every few seconds, it fixes itself until movement starts again (I'd guess that's a key frame, but I'm really not in the know about h264).
On second thought, you might want to move the topic from Panasonic to somewhere else, as this might not be distinctly Panasonic related.
