Sorry Netflix fans, CBS Corp.'s Showtime unit said it is planning to remove some of the premium cable network's shows from Netflix Inc.'s streaming video service, days after the online video distributor announced its plans to offer its own original programming.

Showtime spokeswoman Johanna Fuentes confirmed the plug will be pulled when the current distribution deal expires this summer. Netflix subscribers have limited time to watch old episodes of shows such as Dexter and Californication on the streaming service.

"We're perplexed by this," said Netflix spokesman Steve Swasey. "We have great Showtime shows available on our service, and we expect to continue with those shows. We have a very good relationship with CBS and all its channels."

Netflix will still be able to offer episodes from Showtime series that have ended their run on the network, such as The Tudors and Sleeper Cell.
