Lost Summary Tab on .avi properties

[blueprint]

I hope someone can point me in the right direction. If I right click any .AVI files, select properties and click the summary tab it simply shows "Summary properties are unavailable for the selected source" instead of the usual details about resolution, bit rate, codec etc (in the advanced view that is)

The tab works fine for all other file types (jpg, mpeg, wmv) but with AVI I get nothing.

I know the information is still embedded in the file because if I connect from another XP machine on my LAN to exactly the same file on this PC I can see the Summary details with no problem.

Might have come from installing PowerDirector 6 - read something about it being a registry fix for undeletable files, but all my avis are FINE and i liked using the properties info for speed rather than GSpotting it.

Is there a fix? I installed the WMP10 runtime again as i saw an app install 9 but that didnt work...

An alternative is to use gspot or avicodec. you could even set them up as a default to open avi files if you want to.
