Comment(by anonymous):

 OK. I have all three patches installed. I haven't had time with frontend
 to test live TV yet, but preliminary backend tests have shown that
 recording on both HDHR tuners does not work. It does not matter which
 tuner is used first (including virtual tuners), the recording on the
 second tuner fails:


 2010-04-16 13:41:26.703 HDHRSH(1013A1B7-0) Error: Get request failed
                         eno: No such device (19)

 Recordings on my HVR1800, HD-PVR, and PVR-350 were successful

 Also, recordings made with the HDHR spam with 100's of MB in backend log
 when commflagging or producing the thumbnail for the recording:

 The spam may or may not be related to the patches, as I have seen this
 behavior before, but I don't remember it being this bad.  I also do not
 know what the condition of the recordings is; will check later using the
 frontend.

 I'll do more testing tonight and tomorrow.
