Folks,
I am new to MythTV and have been playing with 0.23RC2 for a while now.
I have two tuner cards:
WinTV NOVA TD-500 (dual DVB-T)
WinTV NOVA HD S2 (single DVB-S2)
I have tried a couple of different combinations of Video Sources and
Input Connections and thought it about time I asked from some advice on
how best to set this up.
I am UK based and want FreeView and FreeSat to both be available for
Recording/LiveTV.
Configuration 1
==========
Capture card 1 : DVB-T Adapter 1
Capture card 2 : DVB-T Adapter 2
Capture card 3 : DVB-S Adapter 1
Video Source 1 : EIT
Input Connection 1 : Capture card 1 -> EIT
Input Connection 2 : Capture card 2 -> EIT
Input Connection 3 : Capture card 3 -> EIT
Setting up Input Connection 1 does a DVB-T scan and returns 86 channels
(FreeView).
Setting up Input Connection 2 uses the previous scan.
Setting up Input Connection 3 does a DVB-S scan and returns 469 channels
(FreeSat).
Recording seems to work well under this configuration but LiveTV is
useless. LiveTV starts on channel 1 (BBC One via Freeview) but as soon
as I change channels to a FreeSat channel LiveTV stops with the error
"Irrecoverable tuner error". While in LiveTV I cannot switch Input or
switch source.
Configuration 2
==========
Capture card 1 : DVB-T Adapter 1
Capture card 2 : DVB-T Adapter 2
Capture card 3 : DVB-S Adapter 1
Video Source 1 : EIT1
Video Source 2 : EIT2
Input Connection 1 : Capture card 1 -> EIT1
Input Connection 2 : Capture card 2 -> EIT1
Input Connection 3 : Capture card 3 -> EIT2
Again recording seems to work well under this configuration and now
LiveTV is better but still not perfect. I have marked most of the
channels as visible=0 leaving 10 channels (5 from FreeView and 5 from
FreeSat) for testing. In LiveTV, when I use CHANNELUP many of the
'invisible' channels can be reached They do not appear in the guide
(neither MFE or MythWeb). How do I stop these channels from being
selectable.
Configuration 3
==========
Capture card 1 : DVB-T Adapter 1
Capture card 2 : DVB-T Adapter 2
Capture card 3 : DVB-S Adapter 1
Video Source 1 : EIT
Video Source 2 : uk_rt (xmltv grabber)
Input Connection 1 : Capture card 1 -> uk_rt
Input Connection 2 : Capture card 2 -> uk_rt
Input Connection 3 : Capture card 3 -> EIT
Now LiveTV is much better but still not perfect. I have marked most of
the channels as visible=0 leaving about 10 channels (5 from FreeView and
5 from FreeSat) for testing. Moving between channels (CHANNELUP etc) is
retricted to the channels on the current tuner for which visible=1.
However, recording seems to be problematic. I haven't tested this
configuration much yet but it seems to me that my recording rules often
record the same program twice. For example, if I set up a rule to
record Jonathon Ross on Friday nights and there is some discrepancy
between the EIT data and the uk_rt (xmltv) data for the show the
recording schedule shows it will record it from both FreeView and
FreeSat (I guess it is being treated as two different programs).
Am I right in thinking that to be able to view DVB-T channels and DVB-S
channels in LiveTV I must configure different two different Video Sources?
How do other people configure this in the UK?
Any help much appreciated.
Regards,
Gavin
