Question on "qscan" (used by "qpxtool" for scanning DVD/CD burn quality)


I'm getting an error in qpxtool that originates from qscan when I try to scan a burned DVD for error correction. It doesn't like something about my LiteOn iHAS124D DVD burner. Or possibly, it doesn't like something about the SATA -> PATA adapter I have attached to the LiteOn (this is a new SATA burner installed in an old computer that only has PATA). The drive reads and burns just fine, so apparently the adapter is working fine, but I suppose there still could be issues running these error correction tests.

qpxtool only tells me that "qScan exited with a non-zero value", so I ran qscan manually to see I could get any more details. Output is below. Any ideas?

Code:
$ qscan -d /dev/sr0 -t errc -s 4
qScan 0.7 (C) 2007-2009  Gennady "ShultZ" Kozlov

I did a bit of digging and it appears that qpxtool is now at version 0.7.2 (released about two months ago). I'm running 0.7.1. Looks like the new version hasn't hit my repos yet, so I'll try downloading and compiling manually. It always pays to try the latest vesion first before extended troubleshooting of an issue. I thought I already had the latest, but it appears not.

So I consider my problem "on hold" for the moment, until I can try the newer version and see if it does the same thing.
