As I'm sure many Nebula users are aware, there is an issue with problematic GOPs in the transport streams recorded from certain channels (ITVC4, C4, five) that means that the files cannot be demuxed by the common programs. The latest version of ProjectX (0.81.7 int1, available from Doom9) is supposed to fix this issue. I have just tried demuxing a channel five recording that I have been unable to correctly process before now, and ProjectX has demuxed it without errors. Unfortunately I'm unable to do a test burn at the moment as I'm at work, but I'll report back later this evening with my results. Fingers crossed, Matt.
