Titolo: Forse FAQ: banda verde in AVI xvid

Sono quasi certo di aver già letto di questo problema, ma da google
groups non ho trovato niente di utile. In queste settimane sto
rippando decine di VHS PAL in xvid senza problemi. Ieri invece ho
rippato un DVD Regione 1 e mi è uscito un AVI di buona qualità ma con
una barra verde lampeggiante sul lato sinistro, la quale è visibile
anche con VLC e MPC, quindi non sembra essere un problema di decoding,
ma proprio insita nel filmato. L'unica differenza rispetto agli altri
film è che qui ho applicato l'IVTC per passare da 30 a 24 fps. Può
essere quello? Ma se lo è, come faccio ad applicarlo senza problemi?

Ho risolto da solo, anche se non so perchè. La prima volta ho
applicato l'IVTC dalle impostazioni di GordianKnot (che vengono
passate ad Avisinth. Questa volta invece ho applicato l'IVTC al
momento della creazione del progetto .d2v con DGIndex (Force Film),
cioè PRIMA di passarlo a GordianKnot, e la barra verde è scomparsa.
Posso solo supporre che Avisinth non gestisca bene l'IVTC, ma è strano
perchè sono quasi sicuro di averlo già usato in passato senza
problemi. Questo il log del nuovo AVI:
