At least twice now, I've found that NRecord.exe was still "recording" a program long after it was supposed to be finished. When I look in the NRecord.log file, I see:
Code:

NRecord is effectively "hung" and no further recording get started until the Recording service is restarted. After the service is restarted that log file end with:
Code:

As I investigated further, I found that the .ts file only contained data for about 15 minutes of the 60 minute show. And, the DCR-2650 network adapter device was no longer listed in Windows. So, I couldn't access the DCR management pages to check on it. Previously, I had unplugged and replugged the DCR power cable--but, of course, that lost any log data in it. So this time, I just unplugged and replugged the USB cable. The network device then reappeared in Windows. And I could access the management pages and look at the log file. Here's what I found:
Code:
20110907-18:59:01 CableCARD: vchannel 879 (537MHz-2) access = subscribed
20110907-19:15:02 CableCARD: out of memory error (cchost_system_time:46)

20110908-02:39:11 System: ip address obtained: 169.254.247.16 / 255.255.0.0

So far, I haven't found the cause of the "CableCARD: out of memory error", but I did find a couple of reports of the same error with HDHR Primes on the SiliconDust site. No report of fix or anything there, just reports of the problem.

Just a follow-up, after some more searching, I've found a few more reports of out of memory errors with the cchost_system_time:46 error. And they all seem have "Emergency message" lines in the log near the out of memory errors:
Code:
20110907-18:54:49 CableCARD: message: Emergency message on TV - tune to channel 6

I submitted a problem report to Hauppauge, so we'll see if they respond...
