The only reason I give this box set one star is because I can't watch it EXCEPT on my computer. For 4 1/2 seasons' worth, I've enjoyed these episodes on my Dynex flat screen. But - and I've had this experience with several other CBS DVDs, for some reason there is some glitch in these DVD discs where they cannot play on my TV set. So BEWARE! I will not purchase another CBS set of DVDs unless I test them at the store first, which is, of course, impossible. I LOATHE playing DVDs on my computer, which I use for - dare I mention it - work.LET THE BUYER BEWARE. CBS IS GUILTY.
