Ah, that sounds good, I now see that this is looking good then because from some added locking and using pio mode for the re-insertion and vbi decoding, I can get really accurate output of the CC. Don't worry about merging, I'll do that, I doubt our changes will conflict anyways since this hits the decoder side. I still see the dropped vbi or out of order packets like your seeing, so reassuring and this no longer seems to output the gibberish where we seem to have been fully over writing our vbi output and scrambling it all up completely.
So version 0.3.4j is an interesting change that locks the vbi decoder bytes till sent, and waits for a vsync to do so, and seems to fix the decoder end of things.
