Pomala NEC NR-7700

[Jiri Musil]

Dobry den,
mam vypalovacku NEC NR7700, ma 12x zapis coz IMHO znamena ze by mela 
palit okolo 108MB/min tzn. "plne" CD do 7min.
Priblizne tohle plati v Neru 5.30 (pod woknama), ale s cdrecordem trva 
vypaleni asi 650MB temer 20min!
Predpokladam ze chyba je mezi zidli a klavesnici...
Nevite nekdo jak primet cdrecord aby palil opravdu 12x?

RH 7.1, distribucni jadro 2.4.2-2
CD-R Verbatim 700MB

Palim prikazem:
