Sorry, I should have stated more clearly that this bitrate-raise is only on the video-pid (pid 101). > I remember Johannes once saying that the EIT rate on the German Das > Erste is quite high. But isn't the EIT on a completely different PID? Thus the EIT should have no impact on this raise. > >I would like to try this recoding (TS->PS). Extracting PES from the TS > >is not really a probem.

But since I need to do it on the fly (since I want live-streams) I'll probably need to roll my own. I found a description in iso13818-1 section 2.5, but this is somewhat hard to read =:) Are any more comprehensive descriptions avalable? -- No software patents in Europe -- http://nosoftwarepatents.com -- Josef Wolf -- jw@xxxxxxxxxxxxx --
