I want to know the answer to the following question:
Some cable boxes are capable of doing what?
All the background I'm provided with is that "Some cable boxes are capable of receiving or recording two or more broadcasts at a time in HDTV format, and HDTV programming, some included in the monthly cable service subscription price, some for an additional fee, can be played back with the cable company's on-demand feature.". Is that enough to answer the question?
Answer: yes
