k3b, failed to change write speed

[pizeta]

All'epoca di kubuntu 5.04 questo errore lo avevo soltanto se provavo a masterizzare dei dvd-video,
adesso con kubuntu 5.10 anche con i cd dati:

Failed to change write speed: 2117 -> 2700

Questo è l'output di debug di kde

So di potermene fregare altamente scegliendo la velocità "ignore" ma questo comporta scrivere un dvd in 1x che tradotto in tempo sono 50 minuti
