The picture shouldn't block up, but you will see MPEG artifacts. Every digital cable system I've seen massively overcompresses the channels. Any fast motion will block up like something you downloaded from the internet.
The delay is normal and is a result of MPEG decoding. MPEG works by not sending every frame as a complete image. It only sends the difference between frames most of the time with an occasional complete frame. The box has to wait for one of those complete frames before it can display a picture.
That's an old box, so the computer that runs it is also slow and will make the menus sluggish. You might ask about getting a HD box. Many cable companies don't charge extra for a HD box. A HD box will work with an NTSC TV and the menus are much faster. Even HD channels look better on an NTSC TV because there are fewer noticeable compression artifacts. The component and S-video outputs also improve the picture.
