Hi Jason, If you go to this page: http://www.adobe.com/training/video.html as you mentioned, you will a subset of the original videos from eTV. The rest of the videos can be accessed, for free, by scrolling to the bottom of the page and clicking on the "explore now" button. You'll be asked to sign in with an Adobe ID and you will be able to search find the rest of the content from eTV PLUS some of the new content we recently developed. We did remove a small set of videos from eTV that were really out of date or were incorrect. If we did remove a video that you really need but that may have been out of date I can try and find it for you and provide.
On a side note, we're looking at our current on-demand training offering and potentially making changes. I'm the product lead working on that and if you have any feedback on what you liked about eTV, what you maybe didn't like and what you'd like in the future I could reach out to you offline. I'm new to the forums but depending on what works for you I can try and reach out!
