So in other words, you want to have the schedule active, but some way to right click on a download and say "force start", or configure it to be "forced" from the RSS feed.
I too would like this feature. Bittorrent programs such as Azureus and uTorrent support this feature for the same reason.
Some TV Shows you just MUST HAVE as soon as they're released, whereas the majority can wait until the scheduled times (usually overnight) and be watched a day later.
I do remember a request like this coming up before, though I think it was related to the RSS feeds, giving alternatives to simply "A" or "D" as actions. Can't remember where it is though...
