Here is the one I had heard of. 

Moonlight
Airs Next: CBS at Friday 9:00 PM (60 min.)
Status: New Series    Premieres: September 1, 2007
Show Categories: Drama, Science-Fiction
More Pictures Moonlight follows Mick St. John, an immortal vampire and private investigator and his struggle to exist with the curse of being undead. It also follows his internal torment as he falls in love with one he should not, one who is mortal and therefore out of his reach, as well as his dealings with the woman who made him a vampire, his sire Corinne. Joel Silver is executive producing with Trevor Munson and Ron Koslow both writing and executive producing and with David Greenwalt as show runner and executive producer.

Good stuff.  Thanks.  Sounds kind of like The Dresden Files but with a Vampire instead of a Wizard.

Hey RIP I saw a few episodes of Forever Night on the SciFi channel.  This does sound similar doesn't it?

Best Buy had the season dvd boxsets of Forever Knight last year and I don't know how many seasons it actually lasted though.

I recall a decent vampire gangster type series on tv called The Embraced or something like that back in the 90's where it was 2 mafia type gangs against each other and they were both vampires. It might have been called The Kindred though.

"To counter its stodgy image, CBS has scheduled a handful of edgy new shows for the fall: a musical, a drama about a vampire and a drama about a Cuban-American family running a sugar business in Florida."

The article didnt not identify if this was indeed title Twilight or not

"Los Angeles-based CBS reportedly is thinking of spicing up its fall schedule with new unusual shows, including one about a vampire detective.  The show "Twilight" is just one of several shows in the sci-fi/fantasy field CBS may be looking at, The Daily Variety reported Saturday."
