Comment (by cehoyos):

 Replying to [comment:9 ramitbhalla]:
 > Hmm I thought the point of -1 in yadif was to "auto" detect

 It auto-detects if the source if bottom-field-first or top-field-first and
 afaict this is also what the documentation says.

 > or should it be yadif 0:-1:1?

 This cannot work: All DVB streams here mark everything as interlaced,
 including 24/25fps (progressive) source material sent in 25i (50 fields
 per second).

 Do you have any reason to assume your input file is not telecined?
