Just when it thought the competition was leveling off, Blockbuster (NYSE:BBI) faces another nasty barrage. The company missed estimates yesterday, now the Street is forcing it to pay.

When you are about to invest in a penny stock, the number one question you need to ask yourself is: What’s the catalyst?

Facing near extinction at the hands of Netflix, Inc. (NFLX) and increasingly popular pay-per-view movies, Blockbuster Inc. (BBI) announced that it would team with on-demand television powerhouse Tivo Inc. (TIVO) to sell and rent movies via digital video recorders (DVRs).

The movie-rental business is in the middle of a digital revolution. Internet-enabled TVs will allow direct downloading of movies. And industry leaders are battling to snap up a potentially huge long-term revenue stream. Andrew Snyder says investors should look to the firms like TiVo (NASDAQ:TIVO) and Sonic Solutions (NASDAQ:SNIC), who sell the technology to make this all happen.
