Incredibly Confused on Mod-Rewrites

[MattClark]

Hi,

I'm trying to redirect

http://www.sitenamehere.com/watch.php?movie_id=($phpvariable here)

to

http://www.sitenamehere.com/watch/movie/($phpvariable here)

------------------------------------------------------------------
Also, watch.php can also be:

watch.php?tv_show_id=
watch.php?episode_id=

And I would like it to turn those into

/watch/tvshow/$tv show variable here
/watch/episode/$episode variable here

I'm currently trying to get it to work for just movie_id, and I was trying:

RewriteRule ^/watch/([0-9]+)$ /watch.php?movie_id=$1

Can anyone point me to why that isn't redirecting anything? Also, how would I change this to redirect movie_id, tv_show_id, and episode_id off of watch.php?

Thanks so much, and sorry for the long post
