I don't see how you are guilty of violating CVC 42003 because you were "never convicted of an infraction". They don't even have proof of service of your 'Notice to Appear.' (unless you received it certified mail).
Were you only mailed one Notice of Violation with no follow-up afterwards?
However, it is possible that when you visited their website, it satisfied 'proof of service' since you entered proprietary information to obtain that video. Once you did that, possibly, it allowed them to file with the DMV if you ignored it. If you did not receive further correspondence from them after viewing the video, that is probably what happened.
