SOMFW, it's not the same thing...
I just tried out
Replay Media Catcher 4.1 and works... it got better than 4.0, which was buggy as hell, never-mind it wouldn't uninstall properly. The difference to what was suggested and what you said is that RMC injects itself into the process and dumps the stream data to disk, where as in non-capture mode the connection would have been re-initiated, possibly raising some flags at MFC. *** and other
screen grabbers only capture the screen that is active, so in front of you. Right now I'm running 9 shows in parallel in the background using stream capture in RMC and all work properly, except some won't load in avidemux but that's OK, they still encode fine with ffmpeg.
One downside is that v4 is not naming the files as 3.1 used to, but luckily the history database is sqlite3 and I'll make some script that renames files to mfc_10xxx... as 3.1 used to.
