Hi all
>From the problems I have had installing it would appear I have digital
cable, Yet when I called the provider they say no it's digital cable
and recommend HRC.
They sent me a frequencies chart
Right now my hookup is as follows:
Cable from provider -->> Splitter ---> TV channel 2-99 (old TV)
|
|
Splitter ---> Computer HVR 1800
|
|
HD Cable Box <<HDMI>> HD TV (Channel 2-1127+)
COMMON EIA Standard IRC HRC Band
CATV T-7 7.00 SUB
CATV T-8 13.00 SUB
CATV T-9 19.00 SUB
CATV T-10 25.00 SUB
...
...
CATV H 21 163.25 163.25 162.00 MID
CATV I 22 169.25 169.25 168.00 MID
CATV J 23 217.25 217.25 216.00 SUPER
CATV K 24 223.25 223.25 222.00 SUPER
....
....
CATV OOO 78 541.25 541.25 540.00 HYPER
CATV PPP 79 547.25 547.25 546.00 HYPER
Just portions of the table
1) How can I prove I have digital or analog cable ?
2) I have the HVR-1800 it has cable three connectors on back plate
Hauppauge says they are for:

FM radio
Analog cable TV
ATSC / QAM digital TV
Into the A/V header I have on the front of the computer an S-Video
and Composite connection
Which is the right one to use ?
3) Using the new v4l-dvb from linuxtv.org
I now have a /dev/video0 and /dev/video1
in MythTV Backend It has in 4. Input Connections
Television , Composite1 & SVideo
Which of the three connectors is Television ?
Right now I have Television -> Cable (video source name)
Composite1 & SVideo -> none
4) Capture Card options Which is right??
Right now I'm using
IVTV MPEG-2 encoder card & /dev/video0
5) Running the latest w_scan 20100316 it starts with
-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_
57000: QAM256(time: 00:00)
63000: QAM256(time: 00:03)
69000: QAM256(time: 00:05)
If I'm guessing correctly this is scanning on frequency 57.000
63.000 and 69.000 If I'm right according to the table given by the
provider there are not channels there the closest are
CATV 3 HRC 60.000
CATV 4 HRC 66.000
CATV A-7 5 HRC 78.000
(a) am I right?
(b) How do I change the frequencies w_scan is looking for
I tried various options and the only thing to change is QAM256 to 8VSB
Thanks in advance
Barry
