I really like the topper video support! My only 'wish' is that we could have an option (by table) in pinballx of which 'media' to use for sound. (options: table audio, pf, back, dmd, topper)
I like using movie/trailers for the topper video, but it won't play audio track from the topper (or dmd as well I believe). I've ripped the just the audio from my topper videos and put them as table audio BUT almost always there's a delay between the audio and video startup so you get 'lip-synced' issues (ie 'audio-delay') ....
so I just have to mute my movie trailers for now....
