> When you install a Linux system, the group ids and user ids are
> assigned to the various groups and users. But they can vary from one
> Linux install to another, even if you use the same version of Linux.
> So if you move a drive from one system to another, you often find that
> the ids do not match and you get the wrong group or user. So you may
> need to chown all the directories and files to what they should be.
> The chown command has a -R option to recurse directories, which helps.
>
> As for your tuners, did you just restore the database without checking
> the order the tuners are in? Tuners can move in order between boots,
> and they certainly move when installed in different slots or USB
> ports, let alone when moved to a different motherboard. So you need
> to see which tuner should be on which /dev/dvb address and make sure
> they are on the same ones that your old system had them. This command
> will show you what the database says the tuner addresses are:
>
> select
> cardid,parentid,videodevice,cardtype,defaultinput,tunechan,startchan,displayname,channel_timeout
> from capturecard order by videodevice;
>
> The videodevice field gives the address of the tuner. So then you
> need to use the adapter_nr option in your tuner driver setup to assign
> the tuners to the correct address. Not all tuners have the adapter_nr
> option, and if any of yours do not, you will need to use udev rules to
> assign them to the correct address. But check first for adapter_nr as
> that is much easier to use.
>
> The modinfo command followed by the device driver name gives the
> options for drivers. Here is what my DVB-T drivers say:
>
> root at mypvr:/etc/modprobe.d# modinfo dvb_usb_dib0700 | grep parm
> parm: force_lna_activation:force the activation of
> Low-Noise-Amplifyer(s) (LNA), if applicable for the device (default:
> 0=automatic/off). (int)
> parm: debug:set debugging level (1=info,2=fw,4=fwdata,8=data
> (or-able)). (int)
> parm: nb_packet_buffer_size:Set the dib0700 driver data
> buffer size. This parameter corresponds to the number of TS packets.
> The actual size of the data buffer corresponds to this parameter
> multiplied by 188 (default: 21) (int)
> parm: adapter_nr:DVB adapter numbers (array of short)
>
> To use the adapter_nr option, you need to create a .conf file in
> /etc/modprobe.d. I have mine in options-dvb.conf. This is what I
> have for my tuners:
>
> #Set adapter numbers for Nova-TD 500 DVB-T card (dual tuners), and
> AverMedia AverTV DVB-T Volar USB tuner (they use the same driver).
> options dvb_usb_dib0700 adapter_nr=0,1,2
>
> #Set adapter number for TurboSight TBS5922 QBOX S2 DVB-S2 USB tuner.
> options dvb-usb-tbsqbox22 adapter_nr=3
>
> #Set adapter number for TeVii S470 DVB-S2 PCIe x1 card.
> options cx23885 adapter_nr=4
>
> Finding the name of your tuner driver can be a bit difficult. If you
> do not know what it is, looking through the kern.log file for what
> happens at boot time will normally tell you, but there are some
> (fortunately rare) drivers that do not actually post any messages that
> have the driver name in them.
>
> If you can not use adapter_nr, let us know and we can try to help with
> udev rules.
>
> It is also possible that your tuner order is stable with each boot, in
> which case you could just delete all your tuners in mythtv-setup and
> re-create them.

I'm not sure this is the command you want:
~$ modinfo saa7164 | grep parm
parm: adapter_nr:DVB adapter numbers (array of short)
parm: debug:enable debug messages (int)
parm: fw_debug:Firmware debug level def:2 (int)
parm: encoder_buffers:Total buffers in read queue 16-512 def:64

parm: vbi_buffers:Total buffers in read queue 16-512 def:64 (int)
parm: waitsecs:timeout on firmware messages (int)
parm: card:card type (array of int)
parm: print_histogram:print histogram values once (int)
parm: crc_checking:enable crc sanity checking on buffers (int)
parm: guard_checking:enable dma sanity checking for buffer
overruns (int)
parm: enable_msi:enable the use of an msi interrupt if available
(bool)
I get:
:~# /etc/modprobe.d# modinfo saa7164|grep parm
bash: /etc/modprobe.d#: No such file or directory
