Is this still working?
15.0.35 (4/29/2010)
1. NEW (Experimental!): Remuxing of television recording (digital television only, i.e. ATSC or DVB-T) jtv files to MKV. Requires Haali Matraska Muxer filter which is part of Haali Media Splitter installation. Select jtv files, and go to Tools > Advanced Tools > Convert Format...
I just tried selecting a file in the Television view, and when I select Convert Format... it says "Please select the tracks you want to convert."
I'd like to archive some programs, and this would be nice to use (I tested it when it was first released and I remember it working then) to handle this.
A better option would be for TV to record to a more "standard" format, so I can set up automatic commercial skipping, but being able to convert/archive to mkv would do for now.
thanks.
