K3B Problema nella lettura di settori dopo masterizzazione

Ciao a tutti, ho un problema con K3B.Quando scrivo un immagine su DVD, la scrittura va a buon fine ma quando il programma rilegge i vari settori dopo la scrittura mi restituisce un errore:
Problem while reading. Retrying from sector 1734912.
Read error in sector 1734960.
Incollo il debuggin output dell'errore in basso.Cercando su Internet ho trovato che forse si tratta di un bug di K3B.Se mi da' un errore in lettura dei settori dopo la masterizzazione significa che la copia non e' andata a buon fine e quindi avrei problemi nell'utilizzare quell'immagine o no?Come posso risolvere?
Grazie

se non usi dvd economici,prova un md5sum per vedere se i dati scritti sono integri,mai usata la funzione di rileggere i dati scritti con k3b.

Credo di capire che si tratti della scrittura di una immagine ISO, se è così controlla il disco masterizzato come indicato qui
http://twiki.org/cgi-bin/view/Wikilearn ... terBurning
è anche spiegato perchè un disco scritto correttamente potrebbe avere un digest diverso dalla immagine iSO originale (e andare comunque bene)
Se col metodo suggerito ottieno lo stesso digest, tutto è a posto.
Alcuni errori nella lettura/scrittura possono essere dovuti ad una qualità del supporto un po' scarsa, hai provato cambiando marca del DVD?
Ciao
