Cut it out.

Last night I caught the last 30 min of "The Fires of Pompeii" a 4th season Doctor Who episode on the SciFi Channel. I had watched the original BBC episode a few weeks ago and with the US release I noticed they had cut at least 2 shots. One was at where the Doctor and Donna were running back to town from the escape pod and they just showed up the house were the Tardis was. They cut the street shot that was in the BBC original. The other shot that was cut was at the very end where had a "Six Months Later" shot of the family that survived. Why did they need to do that? Time? More commercials time?
