hi still not quite getting it
initialised the device with
~$ avcctrl -i -f PAL -t MPEG2 -q BETTER -s TUNER -v 0
then scanning with
~$ avctune -r uk -s 0
but no channels are found- does this need root access?
I have looked into /etc/avc2210k.conf.xml.
as far as i can tell the section for the uk is the basic uhf broadcast band
however I have channels below this in vhf (it's cable)
presumably the entry for the uk needs to be expanded.
because its not finding any channels i dont get a channel list
in windvr the channel list looks something like this
[CHAN_MGR_A]
CHAN_NUM=0
CUR_CHAN=0
LAST_CHAN=0
[CHAN_MGR_C]
CHAN_NUM=107
CUR_CHAN=0
LAST_CHAN=0
[CHAN_C_0]
Name=CBL 002
DspNo=2
No=2
State=0
Lockout=0
FreqOffset=128
[CHAN_C_1]
Name=CBL 001
DspNo=1
No=1
State=0
Lockout=0
FreqOffset=128
[CHAN_C_2]
Name=CBL 003
DspNo=3
No=3
State=0
Lockout=0
FreqOffset=128
.... ect
a typical working channel looks like
[CHAN_C_12]
Name=CBL 013
DspNo=13
No=13
State=7
Lockout=0
FreqOffset=128
essentially state =7 on a valid channel
on a detected but scrambled channel the device falls over after a few
seconds.
with the windvr software its just not possible to deselect a scrambled
channel
so has to be edited by hand. incidentally this is a real pain when recording
from a VCR source a bit of drop out will cause the device to lockup and stop
recording.
I would guess this is the bug you mentioned... Kind of defeats the purpose
of the device
for format shifting from tape to DVD.
I wonder if a TBC placed inline would avoid this. When I get this working i
will give it a try and report back.
so to sum up my current questions are :)
1) what am i doing wrong detecting channels
2)how does the /etc/avc2210k.conf.xml. need to be modified to scan the
wider band width.
3) what is the format of the channel list file and could i create it
manually
4)can any tv programs interact with the device as far as channel changing
goes or is channel surfing out of the question for now.
thank you for your help
warm regards
John
