You can’t say HBO isn’t trying to support its fascinating new weeknightly shrink drama “In Treatment” with a variety of viewing options. But you can say it’s mind-boggling trying to figure them out.

In addition to each night’s new half-hour 9:30 p.m. episode on the main HBO channel — Gabriel Byrne’s psychiatrist sees Melissa George on Monday, Blair Underwood [above with Byrne in HBO photo] on Tuesday, Mia Wasikowska on Wednesday, Josh Charles and Embeth Davidtz on Thursday, and Dianne Wiest as his own therapist on Friday — the series repeats the previous week’s episode/session as a 9 p.m. lead-in. Then HBO repeats the pair at 11 and 11:30 p.m. that night.

Meanwhile, the HBO Signature digital channel runs a day behind for laggards. For instance, Tuesday’s Underwood episodes encore Wednesday at 8 and 8:30 p.m. on HBO Signature.
