My report on the MDP-130, since I just got mine today ...
It works ... and pretty much flawlessly at that. Popped it right in the box a MDP-120 was in, it worked with the MDP-120's drivers, straight up.
Upgraded to 1.65 to get the QAM tuning enabled, and scanned away.
I was somewhat concerned at first that it couldn't tune the same channel (98) that my Fusion 3-T couldn't tune ... it DID fine 8 zillion other channels though. Far Far Far more than Fusion.
Installing an amp on the line (I think it's a 20db amp which may be overkill) cleared up the channel 98 tuning problem -- comcast must simply be weak on that one channel. It's kinda weak on the cable box too - comes up in the Motorola diagnostics as "fair 76%" agc, which is acceptable but not all that good. I haven't tried with Fusion yet, but it might clear that problem up too.
A software note for the MIT folks ...
Here in atlanta, 108-1 is WXIA-DT ... 108-2 is WGCL-DT ... the MyHD picked up channel 108-1, labelled it via PSIP as 11-1 ... then promptly labelled 108-2 as 11-2 ... even though it's a totally seperate station and should in reality be 46-1. I think the software got confused because 108-2 had no PSIP.
WXIA is, btw, the only cable QAM station broadcasting PSIP info.
Regardless, since cable stations are not likely to carry subchannels of a main broadcast station (and if they did, the subchannel would be its own PID, with its own PSIP) the PSIP should apply only to its host PID.
and lastly, a hardware note for MIT ...
My MDP-130 came with the nut that holds on the SPDIF rca jack turned slightly askew ... this is not a manufacturing defect or anything, but what it DID do is orient the nut so it wouldn't fit between the PCI slot edges. Turning the nut slightly so the flat sides of the nut were parallel to the slot sides fixed the problem.
If someone who didn't notice this tried to jam the card into the PCI slot they would almost assuredly damage or possibly destroy the PCI slot and the card, and mostly likely bend the case metal around the slot too.
