Hello everyone,
it is said that .ts transport streams (DVB recordings) include errors, 
error correction data and filler data. Tools like ProjectX (for SD) or TS 
Doctor (for HD) can repair and "clean" the files so they get "better" and 
- Now I read that ffmpeg could do this, too. Is that correct?
- Would something alike "ffmpeg -i input.ts -vcodec copy -acodec copy 
output.mpg" do all of that automatically or do I need to use special 
arguments to enable the "cleaning" (I've only found -err_detect option that 
does not seem to repair)?
BTW: What does it mean having errors and error correction data inside of 
transport stream files? Have the errors already been corrected by saving to 
.ts and only the error correction data is left for some reason or are the 
errors still present and are corrected by the player using the included 
error correction data every time the .ts is played?
