Viacom (NYSE: VIA) issued its Q1 earnings results on Friday. The conglomerate seems to be doing all right with its strategy of leveraging content to drive growth. Revenues were up 15%, and adjusted diluted earnings per share jumped 29% to $0.44. But it can be seen that there's a dichotomy going on if you look into the performance of the two main operating segments: media networks saw its operating income rock up 15% while filmed entertainment tallied up an operating loss for the quarter. Even though that loss was narrowed by over 40%, I always get disappointed when I see a studio in the red -- it reminds me that the movie business is a risky, oftentimes low-return one.

But, should you be down on Viacom's movie business right now? Maybe not, since Paramount is currently distributing Marvel's (NYSE: MVL) Iron Man -- see Sheldon Liber's recent article about the film. That should hopefully improve things going forward, as might Indiana Jones and the Kingdom of the Crystal Skull. Viacom also will be distributing Kung Fu Panda for DreamWorks Animation (NYSE: DWA). Sumner Redstone is certainly counting on these projects to be huge. And speaking of huge, the company's Rock Band continues to fuel the media networks segment -- it's sold by Electronic Arts (NASDAQ: ERTS), and it is apparently holding its own against Activision's (NASDAQ: ATVI) Guitar Hero. The synergies between MTV and the music system are obviously pushing this one. Maybe the studio should get in on the video-game action by greenlighting a movie based on Rock Band -- maybe Jack Black could star in it!

Overall, I think Viacom is performing as it should, and I hope the movie division can bring in some profits during the coming months (I think it will). As for the stock, I'd ideally like to see it a bit lower before I'd consider buying it.

Disclosure: I own shares of Activision and Marvel; positions can change at any time.
