* Media bill expected to pass Senate, but with changes

* Vice President's opposition will not have effect

* Clarin group stands to lose from broadcast reform

BUENOS AIRES, Sept 21 (Reuters) - Argentine President Cristina Fernandez's broadcast reform bill will pass a Senate vote in the next few weeks despite attempts by her rogue vice president to stall it, a political analyst said on Monday.

The bill, which has pitted Fernandez against the powerful Grupo Clarin media and Internet conglomerate, was approved in the lower house but could be modified in the Senate.

Fernandez says the bill will make airwaves more democratic by restricting the number of licenses controlled by dominant media giants. But critics say her main motive is to weaken the Clarin group, whose media outlets have attacked her policies.

"I think the law will pass. They have enough votes in the Senate," said Roberto Starke, a political analyst for Infomedia Consulting.

But Starke said the Senate could make a significant change in the bill, giving media groups three years instead of one to sell off frequencies that would no longer be allowed. That would give companies time to try to overturn the law after the 2011 general election.

Vice President Julio Cobos, who presides in the Senate and who had a major falling out with Fernandez last year over farm policy, ordered the bill sent to five different committees for debate instead of just two that the president had wanted.

He was maneuvering to delay the vote on the initiative until December when a new Congress will be seated and Fernandez will lose her majority.

But his move failed because the orders were not followed before Fernandez left the country to go to New York this week for the United Nations General Assembly, which means Cobos is now acting president of Argentina and cannot act as head of the Senate.

Starke said Cobos' move was symbolic and that the vice president sought only to remain in good standing with Grupo Clarin while firming his opposition to Fernandez and her husband and predecessor ex-President Nestor Kirchner.

Cobos is an opposition leader who Fernandez had made her running mate in 2007 to form a coalition ticket. But as head of the Senate he blocked her key initiative to raise export taxes on the country's main crop, soy, last year, and they have barely spoken since.

He has become active with the opposition and is widely considered to have presidential aspirations. (Editing by Fiona Ortiz)
