Hehe, I got jealous to see you have a nice cdspeed icon in the title bar and not the antiquated wine icon like me, so I checked for another wine update and hey presto, it's there now with 0.9.56. Still no luck with SmartBurn (the Lite-On tool) though. I would be interested to know if that works for you (I suspect it's a graphics problem with my setup and not a wine issue, as it used to work before). Here's a download link (it's a simple executable, no installation required - I prefer the more business-like look of 3.1.1.6t over the newer 3.2.0, functionality is the same).

By the way, you can enable Jitter scanning with the Lite-On under the "Advanced" button (see below). And PIF's go "in the red" above "4" in Lite-On scans, so you'll see well enough when you have a dubious burn (it's to do with the 8ECC scanning interval of the BenQ vs. 1ECC for Lite-On).

A last tip: backup your 20A1S EEPROM with the EEPROM Utility and your original firmware with the Flash Utility and keep these two .bin files in a safe place.
