I had the exact same problem with the new guide a/k/a software......
Some things to know:
When the box flashes 'hold', it really means 'wait' - it is trying to download software from Cablevision. If you disconnect the coax cable, you will sit on 'hold' indefinitely.
As it turns out, Cablevision's new software cannot support HDMI and separate digital 5.1 audio simultaneously. If there's an HDMI cable plugged in, that's where the 5.1 audio gets sent. Period.
The DVR will send digital audio out the fiber connection, but it's not 5.1.
If I were to unplug my HDMI cable or turn off the TV, I could get 5.1 sound via fiber to my receiver.
But then my TV is dark!
Are you kidding?
Am I supposed to go out and buy a new receiver that accepts HDMI?!
One rep at Cablevision even told me the problem must be my Sony receiver, which they don't support..
The tech came on Saturday and insisted on swapping out my DVR. I told him I didn't want to lose all the content on my DVR. I also told him the problem was the software and of course, he didn't like my attitude. I insisted he troubleshoot the problem with my DVR, but he wouldn't listen. He swapped out the DVR and sure enough, surround 5.1 digital audio still didn't work.
When he plugged in my external disc (DVR expander), it came up with a message about reformatting. Before I could even ask if we could see any content still left out on the old drive, he pressed the button to re-format my drive. Thank you very, very much.
He insisted there was an option to select where to send the 5.1 signal - HDMI or not. I told him that option was gone in the new software. Sure enough, he couldn't find it because it doesn't exist anymore.
He then insisted that we try the RCA plug type audio (left right - white red) cable. I told him that is strictly an analog audio signal. There is no way on God's green earth digital audio will be passed via analog. We tried it anyway and of course, it didn't work.
So, he suggested we use component video cables to connect the cable box to the TV. Sure enough, surround sound started working because the HDMI cable is unplugged.
He left extremely pissed off with some kind of attitude. I must have ruined his day by proving him wrong so many times. So, I had to downgrade from HDMI to component video. It turns out Cablevision doesn't support 1080p which requires HDMI cables. The best they can do is 1080i, so having HDMI is meaningless.
If Cablevision had been honest and admitted they had a problem in this area, I would have accepted that. I could have easily re-cabled my box with component video myself and lived with 1080i. But I needlessly lost everything in my DVR. They gave me another Scientific Atlanta 8300 box, just like the one I had. It works the exact same way.
It's the software, guys.
Another problem with their new guide:
Suppose you are watching Jeopardy which starts at 7pm.
The show is in cache because you haven't changed channels.
At 7:15 you decide you really like the show and decide to record it.
You will only record from 7:15 on.
The old software would record the entire show, as long as it was still in cache, and you didn't change channels.
You no longer have the ability to change the start time, so that means you had better know beforehand exactly what you want to record to your DVR.
No more recording on the fly.
Way to go Cablevision, another great feature.
FiOS was installed last Thursday.
After almost 40 years, I have evicted Cablevision from my house.
I have returned their empty DVR without a second thought.
