[18:39] <qwebirc96010> hello, I have a hardware setup with 3 WinTV-HVR-1250 PCIe cards, and 1 pcHDTV 5500 PCI card, but I'm not able to get all 4 of them recording.  All 4 cards are dectected by the operating systems that I have used (mythbuntu 14.04, mythbuntu 16.04), but only 3 of them scan channels and record propertly.
[18:40] <qwebirc96010> The fourth card, which i'm almost certain is one of the WinTV-HVR-1250 cards, while being recognized as a recorder under '/dev/dvb' does not scan any channels (0 channels detected), and so i obviously cannot record anything with it.  So, i'm only able to record 3 ATSC channels simultaneously at the moment, and I'd like to be able to this machine to record 4 ATSC channels simultaneously.
[18:40] <qwebirc96010> so, i'm trying to figure out if there is a kernel device driver paramater for example, the 'cx23885' module parameter, that can be tweaked to make all 4 cards (all 3 WinTV-HVR-1250 cards) working as intended.  So, i'm looking into tweaking one of the 'cx23885' parameters like -  vbibufs, vid_limit, mpegbufs  - to see if any of these will get the desired result.
[18:41] <qwebirc96010> I know I had to set the kernel parameter "vmalloc=320M" to get 2 WinTV-HVR-1600 PCI cards to work on a different machine.  So, i'm wondering if something similar can be modified to get all 4 cards working on this machine.
[20:14] <qwebirc96010> does '#define CX23885_MAXBOARDS 8'  mean that up to 8 WinTV-HVR-1250 cards can be installed on the same system and capable of recording 8 different channels simultaneously??
