Here is why the VC 11 question-----
3.4 Which VideoCipher modules are compatible with 4DTV?
VCII (or VideoCipher II) was the original VideoCipher technology, which was
compromised very early on. Many people modified the VCII module in order to
watch subscription programming without paying for it. This technology was no
longer manufactured after 1989, and was completely replaced by the VCII+
technology in 1993. VCII modules were black. VCII modules are not compatible
with 4DTV IRD's.
The following modules are compatible with 4DTV, but there have been a few
people reporting they have had difficulty getting the VCII+ module to work
with a 4DTV. The VCII+ module should be compatible, but no absolute promises
can be made.
VCII+ (or VideoCipher II Plus) was a more secure technology mainly because
GI integrated a bunch of separate chips into a single secure chip. The VCII+
boards also supported more scrambled channels than the VCII (256 tier bits
instead of only 56). VCII+ modules were originally the lighter color blue,
and then changed to pink to denote that they were covered by the Consumer
Security Protection Plan (CSPP), which guaranteed a free upgrade to VCRS
if the VCII+ security was compromised within the first three years of
ownership. These began shipping in 1990 and stopped shipping in 1992.
VCRS (or VideoCipher Renewable Security) was an enhancement to the basic
VCII+ technology, but added the security card (known as TVPassCard), which
is the replaceable security. The VCRS is shipped without a TVPassCard, but
is designed to accept a card if the base module becomes compromised. In that
event, all base modules without a card would no longer be able to decrypt
the signals. VCRS boards are navy blue or purple to denote that they can be
exported out of the US. The purple modules were known as VCRSi, but were
functionally the same. All VCRS boards were covered by the three year CSPP.
They began shipping in 1992, and stopped being manufactured in 1998.
