Update
Hey, well, I had some success just now. I grabbed the video file using the activity window in Safari as I used to do, but previously I had not taken sufficient notice of the fact that the file is now being saved as "videoplayback". Tube TV would not convert that, but when I added ".flv" to "videoplayback" (videoplayback.flv) Tube Tv was able to convert the file so I can add it to my iTunes library. A bit cumbersome, and I hope Tube Sock can be made to work again, but at least I have a workaround for now.
