One leg of the new Pax TV lineup on KXPE, Channel 50, (see cover story) is the nightly repeat of "Diagnosis: Murder," beginning with the 1992 made-for-TV movie "Diagnosis of Murder" at 8 tonight. Dick Van Dyke's (left) sleuthing M.D. has more spring in his step after the show recorded its best season ever, climbing into the Nielsen top 25 and helping CBS finish ahead of Fox in young adults on Thursdays. Expect to see a lot of Scott Baio; he was a "Diagnosis: Murder" regular during the show's first two seasons. Twice-nightly episodes begin at 8 p.m. Tuesday for two weeks before shifting to 9 p.m. only. Also, tonight is your last chance to see Howard Stern make a mockery of "The Magic Hour" at 11:30 p.m. on Channel 4.
