What we're watching: Tonight NBC plays the is-it-HD-or-not (thanks rocko!) game with The Italian Job, which you would expect to be shown in high-def but isn't listed that way on their site. Titan TV says it is, we'll know for sure at 8 p.m. ABC brings us Practical Magic, while The Longest Yard remake with Adam Sandler hits Showtime tonight. Finally, all the Lil' Bow Wow fans out there can see the skating flick Roll Bounce on Cinemax.

Our traditional high-def listings continue below.
