"Pretty Woman" is strong in the home-video market, clinging to its No. 1 spot on the Billboard rental chart for another week. It's under siege, however, from two of the strongest titles of the year--"The Hunt for Red October" (No. 2) and the Arnold Schwarzenegger blockbuster, "Total Recall," which debuted at a mighty No. 3. Like "Pretty Woman," "Recall" is available at a low $25, which will cut into its rentals since many fans will buy it instead. It's likely that "Woman" will bask in the glory of No. 1 for a few more weeks before finally succumbing. "Miami Blues," which did mild box-office business, is a red-hot rental, jumping from No. 29 to No. 8. Many fans are renting this one to further enjoy Alec Baldwin, whom they discovered in "Red October."
