Bankrupt video-rental chain Blockbuster is seeing its biggest DVD suppliers turn against it in court, reports the Los Angeles Times’ Company Town blog.

The story says Universal Pictures on Wednesday became the third movie studio to submit a filing in Blockbuster’s bankruptcy court case claiming that the rental chain owes it millions in unpaid fees, the story notes.

The claims raise the possibility that Blockbuster will be starved of new DVDs as it continues to run its stores while looking for a buyer, the article adds.

Universal’s home entertainment unit claims it’s owed $6.4 million for the movies it’s sent to the rental chain since filing for bankruptcy, the article says. The other two studios that have submitted claims are 20th Century Fox and Summit Entertainment, it adds.
