I got the dual-tuner version of this last time it was here on woot.. came in much sooner than expected, too!
I haven't tried it with an antenna, still getting around to that, but I DID plug it directly into a friend's cable line (time warner) -- she subscribes to internet only, and I was still able to watch TV.
at first I thought I could only pull in about 7 actual channels that weren't encrypted or what appear to be the video that shows in the corner of the screen while surfing the on-demand menu screens for regular TV subscribers--
then I looked a little further into the software that it came with and discovered there are multiple programs per channel, bumping the actual tv channel number to somewhere around 37. a few of them seemed to be copies of themselves some in SD and HD, I haven't looked into what makes the various copies different that are on other actual channels, but the list I was able to put together is:
[plugging the dual-tuner version of this box into the cable line of a Time Warner internet only cable subscriber (Dallas/Fort Worth area)]
FOX, NBC, ABC, CW, Telemundo, Univision, CBS, MustBe21, KERA, C-Span3, C-Span2, C-Span, TV Land, 5 religious channels, 3 other spanish channels, Ion, WFAA-2, WFAA-3, KERA World, shopping stuff and Discovery.
everything else is encrypted, no data, or not really a channel but instead just advertisement loops for other programming. and one channel that is "reserverd for future use" or something.
and then I took my box back 'cause I wanna use it at home.
I was just using the HD Homerun Config Utility or whatever it's called, and VLC for playback, in Ubuntu, and also in Windows XP Pro via VMware in ubuntu. watching two SD channels (one in each operating system on the same computer [quad core 3ghz, 4 gigs ram] - 1 core and 1 gig going to the VMware guest OS {Windows XP Pro}) is fine. one SD channel and one HD channel at the same time also seemed fine, but two HD channels and things started to get choppy.
now granted this isn't your average everyday setup, nor is it optimal nor practical to watch this way, it is possible and proves it works, to an extent.
as time permits, I will try various combinations of hardware and software, ideally watching broadcast content on one computer with one tuner while a second computer is using the other tuner should more than one person want to watch different things at the same time, or watch one while recording another, etc...
overall I am very happy not even tapping the fullest potential of just the dual-tuner version, and I wish I had known the "good one!" was going to be offered here as now I'm greedy and want to tune and record everything at the same time. not all the time.. but when the next national disaster happens, I'd like to be able to watch and archive it from all the angles across all the news stations.
but the price seems a little high on this one, I don't remember how much I paid for my dual-tuner version, but I wonder if it would be cheaper to have bought more of those ones or a few of these ones...
can someone tell me if splitting off from the cable modem's line would produce better/worse/different results than plugging into the regular TV line for cable internet subscribers?
