Bryan: I was able to read DVDs on the IYONIX with very early versions of the OS, possibly even 5.00. At the time of the release of the Foundation DVD, the IYONIX could certainly read DVDs. The same is true for RISC OS 3.7 and RISC OS 4.0x by the way, something which was also deemed impossible in the RO Ltd. Foundation DVD press release.
I made it clear to RO Ltd. as soon as their announcement was made that it was untrue - after all, statements like this would do potential harm to my business. Indeed, I spent considerable time explaining the truth to confused users. Thank you RO Ltd. for making the life of a software developer even more difficult.
