Yes, can we please get the ability to add in an offset to the audio?
Almost all of my video library is already .mp4 or .mkv files, and yet I get atrocious lagging of the video compared to the audio. That is, the audio is currently about ~500ms ahead of the video. While I couldn't tell you if it's attributed to possible lag on one end or another, possibly TV input lag.
Either way, this type of feature would be extremely helpful and alleviate the problem for everyone else that may run into it.
