Personally I didn't have any problems with Starforce apart from the 5 sec lag before loading. I also downloader and installed SFs new version of drivers, just in case.
CD / DVD burning is same as usual. (Both burner and readers are NEC, with stock firmwares, if this helps anybody)
I have read many times that SF is a problem for some users. In any case this is not the right forum for SF workarounds.
Although I am quite sensitive in things that are installed to my HD against my will (eg I don't use adware. I use mostly freeware apps even if they have inferior functionality), my love for SH3 weighs more than SF fears.
