problémový mpeg2 soubor

Mám jeden dost zvrhlý MPEG2 soubor - z Playstation2 disku, takže obsahuje některé zvláštnosti. Mplayer ho dokáže jako jediný bez problému přehrát jako MPEG-PS(bez zvuku, ale to není problém).Ovšem když ho chci pomocí mencoder -nosound -ovc copy -of mpeg převést do normálního MPEG, tak po určité době dostanu seek failed. Šlo by nějak spustit mencoder, aby začal od určitého snímku? mencoder -ss použít nejde, protože je tam několik "kapitol" a v každé z nich začíná odpočet času od začátku.

Pokud ve vyslednem souboru nepotrebujes zvuk a mplayer tento mpeg dokaze prehrat, pak by mohlo stacit neco jako

 mplayer -vo jpeg soubor.mpg

nebo

mplayer -vo png soubor.mpg

Vytvorene soubory s jednotlivymi framy pak lze poskladat dohromady pomoci ruznych programu (napr. mencoder).

Nechtělo se mi rekomprimovat, ale asi mi nakonec nic jiného nezbude.
