I've been meaning to pull an issues/gaps list out of Jim's summary 
so here's a start:

(my comments are marked JR)

1. Keyboard access to video controls
JR: covered by 4.1 - need to ensure this is clear to reader

2. Scaling video
JR: we talk about text scale in 3.7 but I think we need to add more 
about scaling video and graphics - this ties in with our "large 
printing" issue.

3. Displaying Captions
JR: We may need to be more clear that 3.7 covers captions.

4. When video is native, greater interaction will be possible between 
video and the rest of the content on a page
JR: This means video will be controlled more and more by buttons other 
than play/pause/stop etc. Guidance may be necessary on what to do about 
multiple simultaneous video sources.

5. Selecting tracks (language, etc.)
JR: I think 3.2 covers it.

6. Contrast of video?
JR: This would be a new requirement - seems useful and would apply to 
other graphics too.

7. Spatial navigation in video (e.g. multiple links on a particular 
frame) and also links in captions
JR: Covered by spirit of 4.1 but needs explicit call-outs I think.

8. Temporal navigation of video
JR: Jim mentions might be covered by 4.7. It's also covered again by 
spirit of 4.1. 4.3 is also relevant.

Any issues I'm missing?
