I've come up with a reference point for the OGG burning problem I've been experiencing:
The last build in which I did not get a "command error" while burning OGG files is 9.1.311. Nothing else - up through build 317 - can perform the task. Because I had upgraded from 310 to 316, I dug through the FTP site and installed/tested everything in between AND the lastest 317 build.
Honestly, this doesn't give me a better idea of what's going awry...especially since I didn't comb through the Histories yet...but I'm hoping this at least narrows down the search and makes it possible for someone to take a look...perhaps starting at the changes that went into 9.1.312???
Everything else seems fine for now, so I'm just gonna sit happy at 311 until this is fixed.
Again, system info...
