Clear QAM

I am setting up a DVR with my computer to record TV shows and Movies off the air to watch later. I have a tuner that supports ATSC (OTA), and I have it setup, and working, but since I have a Fioptics TV subscription, I was hoping to buy a QAM tuner, and use it to record shows on my cable subscription.

Does anyone have a list of the channels that are available via clear QAM? I know they encrypt some of the channels, so they are only available via a cablecard system, or setup box. I am interested in the channels that are not encoded.

I have not been able to setup any Clear QAM channels. Connecting the coax directly to the card, no channels are found.

I used to be able to watch all channels using S-Video (component out), but that died with the most recent patch on 1-16-2013. I suspect that they enable the copy never broadcast flag, but have no knowledge on how to prove it.

I have an AverMedia M780 tuner card which supports Clear QAM, component, and ATSC. Right now, all I can receive is OTA channels.

I have an OTA ATSC card that I am using right now, and I just plugged in my Clear QAM card to scan for channels. Nothing yet This make me kind of mad since I am paying for the service (and I just ordered another QAM tuner off ebay).

It seems like it should find some unencrypted since my TV picks up HD channels without a set top box

The channels are definitely there in clear QAM, they are just hard to find for some reason. A few of them show up after each scan, but none of them have any useful scheduling info or anything, so I have to manually link them to channels.

What program are you using? I'm using mythtv.

I've wanted to do similar, but unfortunately, depending on what your Fioptics installation looks like and how it is provisioned, the option to connect a cable-ready TV or any other QAM tuner directly may not even be available. See this post for some info on my installation.

In short, mine is FTTH with IPTV, and as such, there is no RF signal anywhere in the entire setup. If yours looks like this, then that would explain why there are no channels showing up when you scan. I talked to Bell about this, and even pointed them to their own FAQ page that clearly states that you can tune basic channels without a STB, but was told that new installations (at least new FTTH/FTTP installations) would be strictly IPTV.

I have been successful at getting the unencrypted multicast streams setup in MythTV, and I can have up to 3 of those recording at once without any issue. More than 3, and they all start coming up completely garbled, but this is a limitation of my internal network's hardware (an old router that doesn't handle multicast traffic properly...)

Which channels are unencrypted for you? The only channels I get via clearQAM are the channels I can get over the air via ATSC.

Pretty much the same - I haven't checked all of the channels, because I was only concerned with the big broadcast networks and being able to record multiple during prime time. I could get these OTA as well, but I don't have an antenna in the house, so being able to record right from Bell's streams (that I'm paying for...) is nice.

True, I really don't want to record much beyond what is on the main channels, but it would be nice to be able to. I suppose it's nice to know that when I move out, I won't really have a need to get cable since none of the channels will work with my dvr system. Right now I'm using one tuner (OTA only) with an antenna, and the other is connected to my cable. Basically I can record 2 copies of each channel simultaneously since the ones available via QAM are the same as my OTA channels.

Out of curiosity, what dvr system are you using this with?

It's a MythTV setup - one backend with two frontends. With Time-Warner, I had a HDHomerun dual-tuner to record 2 unencrypted RF channels, plus a Hauppauge HD-PVR hooked up to the cable box. Now the HDHomerun is useless (until I break down and put an antenna in the attic...), but I can record 3 unencrypted IPTV streams, plus one from the set-top box.

What connection are you using from the STB? I used the component to my s-video on the card (Avermedia M780). The recent patch they applied to the STBs broke that.

If your's is working, I'd like to get more info.

I'm using component out to my Hauppauge HD-PVR. It is a great device, and works very well in MythTV (and is still working as I'm typing this).

Interesting, yours is working with the component out and mine is not. I wonder if it is the difference in cards or something else. I have FTTN, do you also?

I have FTTH/FTTP, with IPTV boxes (the ZTE ZXV10 B700V3A). I think you said you were using component out to S-video, I wonder if there is something going on in that conversion that is messing up the signal. Also, I don't know if it is the case with these boxes, but with Time-Warner, I found that I couldn't have both HDMI and component output at the same time. My initial setup with Time-Warner was to have HDMI out to the TV, and component out to the HD-PVR, but if I was watching TV, I couldn't record the same on the PVR. So I ended up having just component out to the PVR, and then taking the component passthrough from the PVR, and hooking that up to the TV component input. When we got Fioptics, I didn't bother to try anything different. Maybe the recent update to the ZTE boxes did something similar (I haven't tried it)?

That's a good point - I too have HDMI from the STB to the TV and use the component to S-video to the tv tuner card.

I thought I had unplugged the HDMI cable during my attempts to troubleshoot, but will give that another attempt.

In terms of the component to s-video, I have been using that connection since I switched to Fioptics in March, 2012. I had no issues until this recent patch was pushed out. Tech support was absolutely useless in trying to fix the problem.

I was considering upgrade my tv tuner to a Hauppauge WinTV-HVR-2250, but I wonder if I would be better off choosing a PVR model instead. I use Mediaportal TV Server to record, and view through XBMC.
