Often I'll come across a film that isn't screening in theatres (near me or sometimes anywhere) and I want to be alerted when it is available on DVD. The same could apply for a book or even a CD.
Is there a site that will let me track DVD (book or CD) releases and push an alert via email or RSS when it is available?
There is a service such as the Amazon Feed Generator which will generate an RSS feed from an Amazon search string, but it doesn't seem to work for searches with no results (yet).
The kicker here is that in some cases the DVD release isn't even announced - so essentially the product doesn't exist yet.
I guess I could RSS a twitter search string and/or a Google News alert to be notified if/when my specific string is mentioned - but I'm looking for something a bit more elegant and easy to use/setup.
