Let the hive mind of Engadget get that for you.
"We need a digital camera that can be switched on and fire off that first shot fast. It's not a commonly tracked statistic on any review site, and nobody seems to have this information for every camera. We were hoping other readers could inform us as to what small digital cameras can fire off their first pics in under a second (ideally under half a second). It needs to be small, but mostly, just really quick in operation. Thanks!"
I beleive the way it will prolly work is you subscribe to the rss feed and the podcast/video will download to the folder you have it set to. The you have the tivo desktop software pointed to that video folder and it will go and automatically parse it and add it to your play list.
This way any RSS feed can be dumped to a folder.
