Oh, how I wish I had EWTN!
This would be wonderful to watch.
You can stream EWTN any time you want. The above page has links to streaming audio and video...with streaming rates that will go down to even dial-up rates. (They have an 18k video stream that is blurry / choppy, but it's there. On the other hand, the 500k stream looks almost as good as the cable TV signal)
EWTN usually has a live feed on their website. You might be able to watch it that way.
