Jep.Noi tiedostot sain toimimaan eli kuva näkyi ja ääni kuului
Itse asiassa minulla on tässä 5 DVD:tä, joista kaksi toimii (toinen tosin vain "oikeassa" DVD-soittimessa. ei-toimiva on iso-tiedosto ja en saa sitä a)kopioitua läppärin muistiin, paitsi huijaamalla, että olen tekeväni k3b:lla levykopioinnin, jolloin iso-tiedosto löytyy /tmp/-hakmistosta b)käynnistymään millään playerilla)
Nyt on siis jäljellä 3 murheenkryyniä.
1)mistä näen, että ko. DVD on edes mountattu zydeemiin?
