Por si os sirve,

Uso Hispadvb.

Ademas, ahora el error que meda es:

Audio PTS: first packet 10:49:18.361, last packet 10:54:36.505
Video PTS: start 1.GOP 00:00:01.029, end last GOP 00:05:13.149
!> last video PTS ends before the start PTS of this stream! Sync impossible

-> 505 stereo/jointstereo change(s) detected...

Entiendo lo que pone, pero no se porque.

Mis pasos son:

pongo a grabar con el 2ndstream, pongo el hispadvb a grabar y para parar, paro primero hispadvb y luego 2ndstream.

No se que hago mal.

Gracias.
