ProjectX is a Java based application that can demux Transport Streams used in digital television transmissions. Additionally, ProjectX tries its best to handle and repair faulty streams, and also attempts to show what went wrong during their reception.
- TS demuxer
- can remux in TS, VDR, M2P, PVA
- handles DVB subtitles
- handles teletext subtitles
- Simple cut editor à la vdr
Being written in Java, ProjectX requires that a JRE (Java Runtime Environment) be installed on your system before it can be run. It is known to run fine with both Sun or Blackdown Java (however, no such luck with Kaffe).

Cleaning (Error Correction) with ProjectX
ProjectX does its full power error-correction only if you choose demux. (You could also chose "to TS" but ProjectX's error correction is weaker and de-synchronisation occcurs - a different for each film...) The good thing about the audio and the video files that are created by ProjectX is: they really are synchronised.
One could do all these things also in the GUI, but the CLI has got all one needs to demux (and therefore error-correct):
me@comp:/videos/vdr/The_Long_Good_Friday/2006-09-184.108.40.206.99.rec$ java -jar /usr/bin/px/ProjectX.jar -demux 001.vdr 002.vdr -out /home/me/videos2convert/ -name longgoodfriday
Now one can recombine them (producing an error-free MPEG2 of pretty much same length) e.g. by
mplex -f 8 -o longgoodfriday_muxed.mpeg2 longgoodfriday.m2v longgoodfriday.mp2
Or one can re-code either or both of them and then recombine them.
