Filter files based on last characters

Hi

I'm having a bunch of files which I want to filter:

20121009 1928 - SF zwei HD - Factory Made - So wird's gebaut.eit
20121009 1928 - SF zwei HD - Factory Made - So wird's gebaut.ts
20121009 1928 - SF zwei HD - Factory Made - So wird's gebaut.ts.ap
20121009 1928 - SF zwei HD - Factory Made - So wird's gebaut.ts.cuts
20121009 1928 - SF zwei HD - Factory Made - So wird's gebaut.ts.meta
20121009 1928 - SF zwei HD - Factory Made - So wird's gebaut.ts.sc

I would like to filter my listing so I only get the files with either .eit or .ts in my results. I've tried to enter "(.eit|.ts)" in the filter field and disabled partial matching but for the ".ts" part I get everything which has .ts in the filelist returned. I also tried (.eit|.ts) which didn't help either...

Any idea how to achieve this?

Thanks a lot!
Roger

*.(eit|ts)

Arghh... I feel stupid - nothing more to say... Thanks Leo!
