Criticism
The PIN system has been subject to widespread hacking. Without encryption, the system was easily circumvented by set-top boxes that are able to access individual videostreams when individual stream PIDs are entered. More recently, the PIN algorithm itself was cracked, allowing others to access the service.
Another downfall is that because the application is MHEG generated, if the set-top box was switched off, access to these channels was lost. It is also stated on-screen before purchase that not all boxes are compatible. Another factor is that a few cheaper boxes do not have MHEG support at all, and therefore cannot access the service.

Famous quotes containing the word criticism:
“Homoeopathy is insignificant as an art of healing, but of great value as criticism on the hygeia or medical practice of the time.”
—Ralph Waldo Emerson (1803–1882)
“Parents sometimes feel that if they don’t criticize their child, their child will never learn. Criticism doesn’t make people want to change; it makes them defensive.”
—Laurence Steinberg (20th century)
“The aim of all commentary on art now should be to make works of art—and, by analogy, our own experience—more, rather than less, real to us. The function of criticism should be to show how it is what it is, even that it is what it is, rather than to show what it means.”
—Susan Sontag (b. 1933)
