The weekend's highlights include the best episode yet of "The Strain," major college football games and the MDA Show of Strength Telethon. Here are some viewing suggestions:
1. "The Strain," 10 p.m. Sunday, FX
Fans of "True Blood" and "The Walking Dead" who have not sampled "The Strain" should check out the latest installment. If the "True Blood" series finale was too low-key for you, "The Strain" will ease your disappointment. The vampire drama drops its heroic human characters at a convenience store, where their mettle and ingenuity are tested. "The Strain" doesn't stint on depicting the horrifying consequences of becoming infected with the vampire strain. This is a classic episode filled with building tension, and David Bradley is mesmerizing as the determined vampire hunter. "The Strain" has been one of the real treats this summer.
2. "Big Brother," 8 p.m. Sunday, CBS
With Donny gone, the reality contest loses one of its most compelling figures. Can the likable Nicole hang on in a house dominated by the male contestants? Derrick and Cody seem most likely to make it to the end.
3. MDA Show of Strength Telethon, 9 p.m. Sunday, ABC
The telethon will feature performances by Rascal Flatts, LeAnn Rimes, Aloe Blacc, American Authors, Bret Michaels, Fall Out Boy, Jason Derulo and Sara Evans. The telethon, which benefits the Muscular Dystrophy Association, will air till 11. The telecast will replay top moments in the telethon's history, as voted by viewers. Look for Jerry Lewis in that footage. The presenters include Alyssa Milano, Brad Paisley, Jordin Sparks, Josh Groban, Ludacris, Susan Lucci and Tom Bergeron.
4. College football, ABC, 8 p.m. Saturday
ABC is likely to score in the Saturday night ratings with No. 1 Florida State playing Oklahoma State in Arlington, Texas.

5. "Dorothea Lange: Grab a Hunk of Lightning," 9 p.m. Friday (tonight), PBS
You've seen her famous photos of the Great Depression and the Dust Bowl, but you may know little about photographer Dorothea Lange. This personal "American Masters" profile will change that. The documentary comes from Emmy-winning cinematographer Dyanna Taylor, Lange's granddaughter.
