For this concrete case, since it is limited to one specific channel, there's a good chance that the encoding of the channel breaks some standards limitation. There's also most likely nothing wrong on VDR, as VDR is basically just forwarding data streams. If mplayer does a better job, then its probably more like a bug workaround. Generally, things would be a lot better if the driver/firmware would do A/V resyncing constantly and not just at playback start. That way, A/V desync wouldn't built up, and desync would only happen for a short time. Cheers, Udo
