Jim, Your unfamiliarity with the acronym speaks volumes. DCT = Digital Cable Tuners. Support for same is what many here have been begging for a long time now. I thought 17 might have brought it to the party, clearly it is still has not significant priority to JR. MC 17 is a great product, its only glaring weakness is its lack of support for cable tuners (DCT).. It is patently obvious that if DCT support was going to part of MC 18 it would already be a major part of the planning.
I think maybe you misunderstand the term somewhat. MC supports
my Digital Cable Tuner (a Hauppauge HVR-2250). It also supports digital cable tuners available throughout the world (DVB-C).
It does
not currently support CableCard tuners (Ceton mainly), though JRiver has repeatedly said that this is something that they'd like to support, if it proves possible to do so. Unfortunately, supporting CableCard is NOT a simple process, which is why SageTV and many other competing PC DVR applications never did and never will (directly).
Basically, you have to bow down and kiss the feet of CableLabs, who hates CableCard and wants to destroy it, and pay them a metric crap-ton of money. Some of the original restrictions have been lightened somewhat over the past year or so, but we didn't see a flood of applications supporting the Ceton cards, so I suspect there is a lot more to it than just signing up for API access (and implementing some sort of draconian DRM scheme).
I wonder if CableCard isn't going to be eliminated altogether over the next few years in favor of integrated third-party systems (like what Apple is likely to do)...
