None of my minis will tune in channel that comes in fine on roamio

Advertisements

So, this morning i noticed that i can't tune in to chanel 1915 on my mini. When i tune to it i just get a black screen. If i change away from it and back to it i get a black screen with the blue spinning circle and the mini is locked up and completely unresponsive until I either unplug power or the coax until it says it's lost connection. This happens on all 3 of my minis. The channel tunes in fine on the roamio. I've restarted the minis and the roamio, but the issue persists. Any insights or suggestions are welcomed. Thanks.

 

Update:
Just found another channel with the same synptoms. Also was trying a workaround of recording the channel then watching the recording on the mini and when that didn't work I noticed that those channels on the roamio have no buffer and if I try to record them it says it's recording, but not actually recording and when the recording is stopped the entry in my shows dissapears. So, the channels in question can only be watched on the roamio, not the minis, and only live with no 30 minute buffer... This says to me that the issue isn't with the minis, but with the fact that the roamio can't record, or even buffer, those channels. Wondering if comcast has changed the format of those to something that the roamio can display, buy somehow not record. Again, any help/insight greatly appreciated.

 

Hey, at least for 1915 (HBO Signature HD) it's H.264 and the frequency is 399000 KHz...
I have also found that it is happening on a total of 10 of my HD channels. Haven't checked SD, takes too long and too many of them... Comcast Nashville btw

 

Thanks for trying. To be clear the hbo channel is just 1 of 10 that this is happening on. The others include WGN, DIY, a couple kids channels among others. And all was fine yesterday... actually recorded a movie at 1:45 AM on the hbo channel that recorded fine.

 

From the quick google search i just did on cci never, it seems like even then it could be recorded and watched for 90 minutes. The 10 channels in question I can only watch live and only on the roamio. If you set a show to record it acts as if it's recording, but if you attempt to play it there is nothing there and when the recording ends it dissapears from the my shows list and is not in the recently deleted folder either. Presumably because nothing was actually recorded. There isn't even a buffer on those channels, so they aren't being recorded in any way.

 

Yeah, that's pretty much the only thing i can figure... must be something on the cable company's end. So I guess all I can do is wait and hope... because I'll be damned if I call comcast. There's almost no chance the person I talk to will have a clue, and a high chance they'll screw something else up. Any time I've had to call comcast it takes multiple calls and several hours and there's about a 15% chance the problem is resolved and a 85% chance they screw something else up. One time they put me on a completely different tv and internet package. The new package was actually cheaper than what I'd been paying, so it would have been fine except that they never informed me and added random add-ons to make it the same price I'd been paying before. So I had no idea anything had changed until I looked at the details of my next bill. When I called to fix this situation I was told my old plan was no longer offered so I couldn't go back, and I couldn't get a different new plan because I had been given an introductory offer and would have to wait a year. And when I asked them to take off the add-on packages I hadn't asked for, been told about, or had use for they were able to do that, but in the process removed my cable card from my account somehow necessitating a few more calls... So yeah, calling comcast about it is beyond last resort.

Sorry for the rant.

 

The cci byte value is 0x00 which seems to be the same as all of the other channels...

 

At this point I'm fairly certain that the mini issue is just a symptom of the real issue which is that those 10 channels for some reason aren't being recorded (or buffered) by the roamio.

 

Thanks, if the problem persists that will certainly be a step I'll take before I dare to even think of trying comcast...lol

I've been checking out the diagnostics info for each of the effected channels and noticed something interesting. 9 out of 10 of the effected channels are on the same frequency with a different program number.

1915 hbosig. 399000 KHz program number 9
1862 indieflix. 399000. 5
1816 retroplex 399000. 6
1511 discfam. 399000. 3
1505 sprout. 399000. 8
1345 ovatn. 399000. 2
1325 gsn. 399000. 4
1291 diy. 399000. 1
1281 cooking. 399000. 7

1216 wgn. 381000. 4

Seems like more than coincidence, but the one that's different leaves me scratching my head.

Btw I have tried completely powering down (unplugging) the roamio and reseating the cable card to no effect.
