[mythtv-users] PVR 500 defective?

Thu Sep 29 10:47:38 UTC 2005

 	Well, I played with my PVR-500 a bit last night.  I followed the 
thread here:
http://www.gossamer-threads.com/lists/ivtv/devel/24322?search_string=second%20pvr-500;#24322

 	My card had the 0x60 vs. 0x61 tuners just like the other guy's. 
So, I applied the patch that adds the lines:

    TVEEPROM_KERN_INFO("Second (radio) tuner idx %d\n",
                                                    eeprom_data[i + 2]);
 	to tveeprom.c.  It does seem to work now.

 	I don't know if that helps your problem.  In fact, I haven't even 
figured out how that patch really does anything... it appears to only 
printk() a debug message.
