i still got this problem with Ubuntu "Feisty" and QPxTool 0.6.09 and Ubuntu "Gutsy" with QPxTool 0.6.1.2. Everytime i try to start a DVD PIE/PIF Scan with my NEC 4550A the message is "All tests complete" although no test is done.
Along with the NEC a BenQ 1655 DVD Writer and a PLEXTOR 5254 CD/RW Writer is installed on the system.
The only way to start a PIE/PIF Scan with NEC or BenQ is to use the PIONEER-Commands in the section "media". But the results are definetly wrong and reading speed is to fast.
Hope you can help, because i don't like to start Windows everytime i want to test my DVDs!
