Warner wants its products distributed via more modern methods

Guba's website allows users to upload their own home-made videos and view those placed by other people.

It will offer Warner Bros content at prices starting from $1.99 (�1.10) for unlimited viewing in a 24-hour period.

Warner Bros and other film companies are tying up with web firms as they look to boost sales and combat piracy.

'Stupid tricks'

They also hope it will help them tap into a younger, more technology-savvy audience.

Tom McInerney, co-founder and chief executive of Guba, said that good quality content will be key to attracting consumers.

"Nobody is going to pay for a video of a dog doing a stupid pet trick," he said.

As well as short-term access to films, Guba users will now be able to buy new movies, such as Syriana, to keep for $19.99, and older titles for $9.99.

They will have to pay $1.79 per episode of a telvision show.

The TV progammes and films can be viewed as a streaming video or downloaded to a portable device that uses Microsoft's media software.
