I was looking at this page in the Wiki, where in the section "Supported Tuners" it says:
It may be worthwhile checking which version of the Hauppauge driver you are using. The Wiki is of variable quality, and parts of it have not been updated for years, so the above statement in the Wiki may now be out of date or no longer relevant.
Also, from your screen shots it looks as though MP is correctly identifying your Hauppauge tuner box, and the scan does find channels with names that look believable. There do not seem to be any other settings that need to be set correctly. So if the driver is up to date, it looks to me as though the problem is that your cable provider encrypts most or all of the channels in the way that MP cannot decrypt, and your only solution is to remain with WMC (using Schedules Direct plus EPG123 to get the EPG).
