If you get the channel HDNet, they show 2 episodes of JAG every weekday from 3-5PM.
The best part is (besides being in gorgeous HD!) there are no commercial breaks!!
It's like watching it on DVD without having the DVDs!
"Lifeline" and "Mutiny" were on this afternoon, so Monday'll have "Adrift Pt. 1" and "Adrift Pt. 2"
