Try TvOnline (last I looked there were two different versions kicking around, one works, one doesn't), it's yet to let me down when looking for a show to watch.
Some of the streams for lesser known/much older shows are a bit shocking but that's to be expected really.
Do you use Genesis in the UK? I find that it absolutely refuses to work for me so I use TvOnline instead...though I hear such nice things about Genesis...
