S.R. writes: A handful of European theater chains — two each in the U.K. and Germany — are boycotting 'Night at the Musuem' and 'Eragon.' The reason? The relatively short window between the theatrical and DVD releases. 'Night at the Museum' is set for a DVD release 13 weeks after its debut, and the theater owners are blaming the short windows for the decline in theater attendance. But their problems are much bigger than that. 'Tickets are expensive, lines can be long, while popcorn and pop cost an arm and a leg. Perhaps most irritating, movie starting times are treated as mere suggestions by cinemas who use advertised start times to launch a barrage of previews and advertisements upon their audience. Once the movie starts, we are then treated to whispered conversations and cell phone usage.'
