Not sure where to post this, please move if necessary. When searching either MP4/8 or MP4/13, no results come up, which isn't the case since there are definite references to it, and it does find it via Google search on the site (site:forum.studio-397.com "mp4/13", for example).
Searching for MP4/8 returns 9 pages of results for me Edit: searching from the forum home page returns zero results, if I view a post then it works from there.
