I have the same setup. It caused me quite a bit of head scratching with this also. The Samsung listings are the actual tuners. I assume Samsung is the manufacture of the chip used to tune the frequencies and Hauppauge makes the complete package. That being said, you want to focus on the samsung frontends as your tuners and ignore the Hauppauge options.
I'm sure you're getting confused with the various muxes that show signals but don't do anything. I have a ton of those listed, but they're not really channels. They really threw me off. I'm honestly not sure what's going on there. They may be radio signal. However, theREAL TV channels have MuxIDs and signals. I went through and changed the check boxes to only enable those feeds with MuxIDs. If you click Play link on one of those rows you'll get the option to download the stream indefinitely (you can drag the *.part file stream into vlc or a media player and watch the life feed).
Once you start limiting your muxes to the ones with MuxIDs, the options under Services will start limiting to mostly functional channels.
Under Services, you may be tempted to only check or enable one item from each frequency, but that would be a mistake. Each frequency can have multiple channels under their frequency. I added numbers for the channel names and then browsed them in XBMC to narow down if the channel was actually functional and learn the real channel name.
Once I figured out what worked and what channels I didn't want, I disabled the frequencies I didn't want (Probably not necessary with what I did next). I then went into Channels under Channel/EPG section and renamed my channels and deleted the channels I didn't want.
I hope this helps.
I'm mostly up and running. I haven't figured out how to get program guide stuff yet. I manually named all my channels. It was a bit tedious.
My major problem is I can record through the browser menu, but within XBMC I don't have the options to pause, rewind or do any of the PVR functions with live TV. My record button isn't working on my MCE remote, either. Yet, I can record within XBMC if i navigate through the on-screen menu.
It's fun to figure it out, but it's not always obvious what's wrong.
