It's been a couple of days, so I figured it'd be best if I did some digging. And I have some great news; I managed to find the schedule for SDCC@Home (with a little help). I also have some interesting news on how to view the panels. It seems on any of schedule pages, there are YouTube links displayed with each panel scheduled. The videos right now are set as private, but my best guess is that these are prerecorded videos of each panel that will be set as public on the date and time they're supposed to premiere. This is just a theory for now, but it's the best I got. Here is the link to the page:
