<strong><span class="infobox-head">TUESDAY </span></strong><br /> Two pieces of good news for fans of the Canadian import <strong>&ldquo;Flashpoint&rdquo;:</strong> The show was just picked up for 13 more episodes, which will air later this season. And in case you missed this summer CBS series focusing on a tactical response unit and co-starring Hugh Dillon and Enrico Colantoni, the first season is out today on DVD.</p><p><strong><span class="infobox-head">WEDNESDAY </span></strong><br /> <strong>&ldquo;Mary Queen of Shops&rdquo; (8 p.m., BBC America)</strong> adapts Gordon Ramsay&rsquo;s restaurant-reboot concept, inevitably I suppose, to broken-down retail stores. Mary Portas, a marketer with a tart tongue, walks into unpopular boutiques and, after quarreling with the owner for a half-hour or so, persuades him/her to do the simple but necessary things to make it work. </p><p><strong><span class="infobox-head">THURSDAY </span></strong><br /> <strong>&ldquo;Meet the Past&rdquo; (8:30 p.m., KCPT)</strong> highlights Crosby Kemper&rsquo;s library talks with famous local figures. These edited half-hour conversations not only give you insights into the lives of Walt Disney (this week&rsquo;s guest), Amelia Earhart (next week&rsquo;s) and others, but also a chance to see some of the area&rsquo;s best historical performers do their thing. If you missed last week&rsquo;s conversation with Harry S. Truman, it re-airs at 9:30 tonight on KCPT and 7:30 p.m. Tuesday on digital KCPT2.</p><p><strong><span class="infobox-head">SATURDAY </span></strong><br /> <strong>&ldquo;Head Games&rdquo; (8 p.m., Science Channel)</strong> continues the trivialization of the once-austere Science Channel. This low-budget game show featuring Greg &ldquo;His Generation&rsquo;s Wink Martindale&rdquo; Proops has three contestants guessing answers to multiple-choice and true/false questions of dubious importance. Will a 50-pound ball of Silly Putty bounce or explode when dropped from a building? Actually, it kind of bounce-explodes &hellip; but seeing as how questions are worth $200, why make a fuss? The top two guessers compete in a lightning round in which, alas, actual lightning is not used.</p><p><hr class="infobox-hr-separator" /> <div class="infobox"> <strong><span class="infobox-head">TUESDAY </span></strong><br /> <strong><span class="infobox-head">WEDNESDAY </span></strong><br /> <strong><span class="infobox-head">THURSDAY </span></strong><br /> <strong><span class="infobox-head">SATURDAY </span></strong><br /> </div>
