Clipbins

I have a problem with clipbins. I select clips and put them together into a bin. These bins are presented to the visitors of my website. Surprisingly, when I click for it, a mass of other clips are mingelt between, which have nothing to do with the selected clips I put originally into the bin. Other selected clips don’t appear at all. Also, the bin was for example selected only for “Pal”. But suddenly all kind of formats are in the bin. Just randomly, not complete.
That is for my site visitors very annoyingly, because I try to present a clear Clipbin, but my visitors have to scroll through a mass of formats to find what they want.
I tried to find an answer in the forum without success.
I tried to access P5 a few times, but did not get any answer. Has somebody similar problems?

I think it is now about 2 month since I discovered the problem. After that I corrected the content of bins, but somewhen later I found the "aliens" again. Not necessary the same ones. I have a suspicion: The files which intermingled have some of the same keywords. Example: ClipBin about "Golf" contains clips about "Construction" and these are about building a "golf course".
I will now contact Marcus directly. Thanks for your suggestion.

The format limiter thing (what pops up when you click the search box) is not part of the url, instead it sets a cookie. We get away with this by letting google always see the default search (all formats, pal/ntsc/hd/multimedia).

Anyway, you can add flag bm to the search result url to force pal, ntsc, hd or multimedia.
