[vdr] Scanning and channels.conf problems

[anthony kelly]

Hi

I am not sure if I should post this to vdr or to v4l/dvb as I'm not sure 
where the problem lies.


One of our local TV stations changed their broadcast configuration as 
follows:

"Guard Interval will change from 1/8 to 1/16
 The FEC will change from 2/3 to 3/4"

To get this channel working again, I tried to scan a new channels.conf.

I changed the transponder file au-Darwin appropriately.  Before this the 
scan did not see the 2 channels from this station at all, after the change 
it did.


However, neither vdr or tzap is able to lock onto the config output.  The 
errors are respectively:

VDR:  frontend 0 timed out while tuning to channel 17, tp 557
TZAP: ERROR: error while parsing inversion (syntax error)

The dvbscan I used is from csv in 19/12/2005, all other channels work fine 
with the channels config output.  I got the latest DVBAPPS and found that 
dvbscan no longer exists, but "scan" seems to replace it.  However, scan 
produces a different output again, and vdr will not tune to any channel from 
the resulting output.


I have a friend in Darwin who changed his au-Darwin transponder file in the 
same way and scanned and got workable outputs for him.  But his 
channels.conf entry for this particular channel doesn't work for me either.


In the past I have noticed that both he and I have different channels.conf 
formats but they have both worked find so I never worried about it. He and I 
were both on VDR 1.4.X also.


Sorry if I am wandering here, I have tried so many things that I don't know 
exactly where the problem lies.


In summary:
-the latest scan utility generates output my vdr cannot read (1.4.1 or 
1.5.1)
-the older dvbscan utility generates output that works for all channels but 
one
-my friend does the same thing and gets channel configs that work for him on 
all channels, but not for me.


My config is:
Debian 2.6.14.4
vdr 1.5.1
Compro DVB300-T tuner (SAA7134)
v4l/dvb from csv (I think) from 14/6/2006

My latest scan output is:

The last 2 entries (SCTV*) are the ones that do not work.

They differ from the rest in the order of the parameters (i.e all the others 
are IxBx whereas the onex that donw's work have the B* much later).  I have 
tried to manipulate these manually to match the others with no success. 
Also interestingly the guard interval is scanned as 8 instead of the 16 it 
should be.


Any ideas are welcome.  I am at a complete loss.

I have very old card drivers, could this make a difference (I tried new ones 
but couldn't get them compiled).


Thanks in Advance

Anthony Kelly

Absolutely, since (if this insanity really happens) it means that
projects like VDR are effectively dead in the water :(

I find it hard to believe that TV networks will be happy with
invalidating every piece of DVB hardware sold to date (and selling now),
but it will all come down to how much pressure MPAA and friends can
bring to bear on them.

Cheers,

Why do you believe that?

Personally, I don't think there's any need for panic.  Too much money
involved.  How many times has something been the threat to end it all,
only to wind up a fizzling dud?  Take these things with a grain of
salt.

Hello.

Thanks a lot to Erik for this info (I have forwarded to news french site, 
because, I live in France :), so .. )

An offtopic message is not inevitably a spam,
in my humble opinion.
A real name, or a pseudo is better that an unix current user I think, that's 
all.
And god is Klaus, here ;) .

Dead in water ?
No.., we don't, we are the custumer at the end of the chain, so..
(not Micro-bidule, no black-box, never, never ;) )

But there are industrial project that's need more publicity...,
(I think to the dead TCPA/Palladium chips in the past, but I'm not up to date 
on it. ).

Regards.

Yvan.

Sorry about my other reply which I accidentally sent without editing.

The trouble is such a thing really has happened to MS Windows. If the
MPAA are powerful enough to force Microsoft to cripple Vista they can do
it to DVB too. OTOH maybe Microsoft didn't take any forcing as they're
part of the same electronic publishing axis of evil, and can make
Windows as awful as they like because of their virtual monopoly. Here in
the UK I'm sure Sky TV would be thoroughly in favour of DRM etc.
