Cannot Record Two Simultaneous Programs

[tjb]

Sub,

I generally never use Live TV, so I had not tested it with Npvr up until this point. After additional testing, it looks like Live TV will always work the first time (after a reboot or restart of Nrecord). If I escape out of Live TV and then restart it, I get the error "Unable to Communicate with Recording Service". Any further attempts will then report the error "Failed to Start Stream". I have attached log files that reflect trying to start Live TV 4 successive times immediately after a reboot of the system.

I still think it must have something to do with my HDHR setup, but for the life of me I cannot figure out what it could be. There are not that many options to configure, and no options when installing the drivers. Seems like the tuners are not reallocating or something? Anyway, hopefully these logs will show something.

It appears when it works, the log shows the following:

Removed (thought changing one of the decoder settings fixed the problem, but it didn't)

I'll be setting up the test platform either tonight or tomorrow (most likely tomorrow).

Is there any resolution to this problem? I have the same symptoms as OP, intermittent failure of second recording and a crash dump message. Same HDHR and Win7. It has been happening for quite awhile, but I'm just now trying to fix it.

After setting HDHR application to "GBPVR", I can no longer make this happen on demand. I'll report back if I get any random messages about crash dump files in the future.
