digital cable is NOT hackable.
the only known trick is for free pay per view movies which works only 50% of the time. i order cricket often, and ive been charged for some, not for others.
you need a thing called a digital cable filter (sold on ebay for about 99 cents). what that does is prevents the box from sending information OUT, but lets information IN. when u order a PV movie from the box, NOT calling in. the information comes in, but the filter blocks the info from going back to videotron.
the memory stays in the box however. if u remove the filter, the data will flow right though and, u will get cahrged for everything. so u need to learn how to reset ur box. there are several ways on teh net. when i had the regular box (non HD) i knew how to reset it, and it worked maybe 70% of the time. now with the new HD box i have, out of about 5 movies, i only got 1 free. it doesnt reset properly.
seach for google on digital cable filter, and scientific atlanta box reset, ull find something.
but its really not worth the risk..if illegal is what ur lookin for, satelite is teh way to go.
