is it a proper HD conversion, or are they just showing it in the original format??
It is in 4:3 format, but it seems to have been a very well-preserved copy of the original. There are some incredibly high-quality tapes available, some of which are featured in the "greatest games" DVD collections found in the NHL store. There are many more that the public does not have access to; if the Canucks ever win the Stanley Cup, we should expect a "ten greatest Canucks games" DVD to become available.
