Yup, well thats almost true, my original problem were "illegal field in parameter" errors, which I btw fixed with RAW/DAO write. However this could very possibly fix pony's "session fixation" errors, as they appear to be caused by improper use of TAO. TAO or Track-At-Once is used to write all the sessions separately and can even be burned at different times, so it looks like TAO is trying to split up the 2 or 3 sessions on the CDI and probably leave empty session space in between thus going against the CDI's original settings and causing those errors. So my suggestion is that you do use RAW write to burn the CDI exactly as it was meant to be. If you still get some kind of errors, then I'll be glad to help out some more.
