XMM: Probably the most powerful movie manager around, let’s discover it’s power:
Is it really? Lets see
Ease of Use
There are a variety of ways to get your Movies and TV series’ into XMM. HDD Search and Importing from text is probably the most useful ways. Once that is done all you do is click on the Internet Update button which then asks you what you want to update. Then you are given a choice of sites to use (e.g. IMDB, AnimeNFO, TV.com) to get all the information of the movie or program. The updates are done with a script that you can easily edit, or you can even create your own.
Accuratness of Import
Sometimes it does get it wrong, but this is usually caused by the site that is searched. IMDB has the wrong information for a search done on Imposter, due to the fact that here in South Africa Imposter is a different movie to the one in the US 🙁
I have had a few problems stability wise, but even though it has crashed, I have not lost much(if any) information. I attribute this to the fact that he is currently using an Access MDB file as the database, but there are plans to change this to something else (going by the support forum)
The Author is giving very good user support. In this month (May 2006) there have been 3 updates to the app, and they where not all bug fixes. Quote a few features where added. There is also an update feature built into the app that can search for new update scripts.
My personal opinion of this is high, I would give it 8/10.
