The only thing that might have been of note is that there seemed to have been a wierd Power Blip, and my linux machine was off when I was not expecting it. After turning it on, I noticed the problem. However, it seems wierd to me that a power blip would blow both QAM cards, and yet leave the ATSC and the PVR-150 alone. (I also have a PVR-150 attached to a Motorola DCT-2524 in that machine). My biggest problem I have right now is determining if there is even any clear QAM available. I did a dtvscan -q from both cards, and neither card is able to lock anything. Before last week, I was able to get locks on many multiplexes, even those populated completely with encrypted PIDs. (I would do an azap in one window to lock a multiplex, then I could do a dvbstream in another window, and run tsreader on my winxp box to actually look at a stream. Encrypted streams would show up as read w/nothing to look at. Clear streams could be clicked, and would play in VLC, so I could see what it is.) I will run another dtvscan to make sure things aren't there, but is there any other means of determining the state of things QAM? Somehow my Motorola DCT-2524 seems to still see channels and work fine, so if Comcast did change something, then they did it so that it doesn't affect their STBs. I suppose my next test when I have some time is to change the ATSC feed from my air2PC card to my Avermedia A180 to see if the card itself can still see the ATSC signals, and make sure the tuner didn't get blown. Guess I'll also have to swap cables around on my 8 channel amp (An Electroline FT08100 8 channel active splitter/amp). --------------040609050503060303020802 Content-Type: text/x-vcard; charset=utf-8; name="mark_paulus.vcf" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="mark_paulus.vcf" YmVnaW46dmNhcmQNCmZuOk1hcmsgUGF1bHVzDQpuOlBhdWx1cztNYXJrDQpvcmc6TUNJO0xl YyBJbnRlcmZhY2VzIC8gNDA0MTkNCmFkcjtkb206OzsyNDI0IEdhcmRlbiBvZiB0aGUgR29k cyBSZDtDb2xvcmFkbyBTcHJpbmdzO0NPOzgwOTE5DQplbWFpbDtpbnRlcm5ldDptYXJrLnBh dWx1c0B2ZXJpem9uYnVzaW5lc3MuY29tDQp0aXRsZTpNYXJrIFBhdWx1cw0KdGVsO3dvcms6 NzE5LTUzNS01NTc4DQp0ZWw7cGFnZXI6ODAwLXBhZ2VtY2kgLyAxNDA2MDUyDQp0ZWw7aG9t ZTp2NjIyLTU1NzgNCnZlcnNpb246Mi4xDQplbmQ6dmNhcmQNCg0K --------------040609050503060303020802 Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ linux-dvb mailing list linux-dvb@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb --------------040609050503060303020802--
