Trying to set up another site. Conversion errors again.!!

If I use ftp to put a FLV or MOV format file in the import folder, the files add to the site correctly when done as admin. OK so far.

If I upload a file (flv or mov) WITH spaces in file name then I get notified "Your video was successfully added!" However I have realtime processing turned on and no cron task. When you check the process queue as admin you find there is an error.

Clicking convert now indicates the file "1 2 3 4 5.mov" or "x y z.flv" is not found. It has not even been moved to the videos folder.

Upload files that have NO SPACES in the file name and everything works correctly.

What is going on?
