Sony Ericsson Xperia X10 :: Mediascape Performance / Disable Face Recognition Service Entirely?

For some time ago I updated my X10 to Android 2.1 and today (a week later) I noticeed all the sudden that Mediascape has linked alot of my pictures stored in my phone to some of my Facebook contacts automatically. Of course Mediascape got it all wrong, linking my children to old friends I haven't met in several years etc. This raises a couple of questions:

1. First - how do I disable Face recognition service entirely. I find this very unuseful since I have found it not that good at identifying persons even when trying to learn.

2. How come that Mediascape did this automatic link between my Facebook contact and my pictures?

3. Is there a way to clear this linking data that Mediascap does. It's pretty time consuming to have to go through all Facebook friends and select the image and Delete the link between the photo and the friend.

I guess Mediascape must have downloaded images from my frieds facebook galleries and analyzed them somehow. However this isn't something I want my phone to spend time doing. The battery time of my X10 is poor already, it doesn't need to do image processing - at least I should have the option to turn this off?

Overall I find Mediascape pertty crappy. Mostly because it's performance. I guess the ideas behind it is good, but the implementation isn't near good enough.

For example, slow browsing between images. Compare with iPhone, Samsung galaxy, HTC phones, older SonyEricsson phones such as W715 or C905. All these perform much better. Is there a way to remove this or use another media viewer?
