Looks like you're using TortoiseSVN. I had the same problems and had to give up with it and switch to using GIT tools (TortoiseGIT and msysgit in my case).

EDIT: forgot to mention that you should either use
github.com/mamedev/mame.git or github.com/mamedev/mame/trunk
so that you don't download all those useless branches.
