Downloading Youtube with safari issues..

Lately I've had an issue when trying to download videos in safari.

i've done it as always, going to window -> activity -> picking the file (usually a larger one) ..

The file then goes into my downloads as "video playback .flv" or something similar, but when opened its all code...

input / advice?

Thanks
Neil
