OP is OmniPatcher. You can get it at http://codeguys.rpc1.org/patchers.html. You can also find a lot of other good stuff at the site including the the stock firmware that you will need in order to OP it.
Remember: Flash at your own risk. (I always feel the need to say that but, in actuality, it is really quite safe.)
If you stay with US0Q, unzip OP (with other files) and the stock US0Q firmware to a folder. Run OP, click the Load button and load US0Q.bin. Click the "Apply recommended DVD media tweaks" and click the other checkboxes you would like. I chose "Enable auto-bitsetting" (if you use +R/RW media, you definitely want this one to set you Book Type to DVD-ROM. It doesn't do anything for -R media.), "Ealier shift" and "force-shifting". Save the file and then use a firmware flasher (found in post 1 of this thread http://club.cdfreaks.com/showthread.php?t=83294) to put the firmware in the drive.
If you go with the CG?? firmwares, they are already OP'ed so you don't need to mess with them.
Do i take it that i should choose the disc's i want to burn with and then set up the drive accordingly ?
What happens if i then try another disc do you have to reset it for them also ?
You shouldn't have to. The recommended tweaks are a compilation of the best experiences from many users for many media. The only time you may need to do this is if you find some certain media is just burning like crap. In that case, you post your KProbe scan here and people are usually more than happy to help (as long as you have done your homework first).
The EEPROM resetting is usually only used when things just go REAL BAD and you want to start again at square 1. I have never personally needed to use it.
Also, if you have read enough in this forum, you will find the drive needs to do a few burns on the same media for it to "learn" how to burn it well.
I feel the fog getting thicker
Yes, it does that for a while but it will lift. You just need to do a lot of reading/lurking in this forum.
Hope this enough info to get you going. I must sign-off now. Keep us posted and good luck!
