AOpen DOES SD2 !!
Ahh, found it. I remember awhile back that CloneCD had an "Amplify Weak Sector" feature that enabled CloneCD to do SD2 backups even with drives that weren't technically SD2 compatible. In the US and UK you are not allowed to use the AWS function and it isn't "available" although you can see it (it's greyed out).
But, if you set your Region setting in Windows (yes, it works in XP) for Canada, then pull up CloneCD, you will be able to access the Amplify Weak Sectors box. I've tried this and it does indeed work. Remember, this box only appears when you are writing a CD.
Also, you can do a registry edit to enable the AWS box or you can download CloneAMP to make the changes for you. Not all CD-RWs can use the AWS feature. BUT the Aopen CAN!
Please check out the following links.
For those Aopen people, I wouldn't be disappointed one bit. I just wish I'd thought about looking at this earlier before wasting my time hunting down a frickin' Liteon.
