There's no stopping "Sherlock Holmes."

Aided by a dearth of new high-powered theatrical releases, the Warner Home Video actioner remained on top of the national home video sales and rental charts the week ending April 18.
 
"Sherlock" had no real competition for the top spot on the Nielsen VideoScan First Alert sales chart, snagging the No. 1 for the second consecutive week. 20th Century Fox's "Alvin and the Chipmunks: The Squeakquel" and Warner's "The Blind Side" also repeated at No. 2 and No. 3.
 
The top-selling new release, the 20th Century Fox comedy "Crazy on the Outside," debuted at No. 4 after a limited theatrical release. The film marks the directorial debut of Tim Allen and opened in theaters without being screened for critics.
 
On Home Media Magazine's rental chart, "Sherlock" was No. 1 for the third consecutive week, with a modest 18% dip in rental demand. As they did on the sales chart, "Alvin" and "Blind Side" again finished at No. 2 and No. 3, with demanding slipping 18% and 24%, respectively.

"Pirate Radio," a comedy from Universal Studios that generated $8 million in theaters, debuted at No. 4, while "Crazy on the Outside" bowed at No. 10.
 
On the Nielsen VideoScan Blu-ray Disc chart, "Sherlock" regained the top spot after spending a week at No. 2. The previous week's top-selling Blu-ray Disc release, Warner's "Lord of the Rings: The Motion Picture Trilogy," fell to No. 5.
