The auction of online video site Hulu has been slowed by recent developments which could derail it completely, according to sources familiar with the process.Among the issues are conflicts over complicated digital rights, a wide bid-ask gap, and Yahoo being sidelined as a potential buyer by its own issues. Moreover, NBC Universal’s hiring of Morgan Stanley banker Stuart Epstein, who was involved in the sale process for the bank, as its chief financial officer complicates a potential deal. @Yungjohnnybravo @TatWZA
