Hauppauge Nova-T 500 & retuning

This dual tuner device has been running fairly happily in my system for a
few years until now.

Retuning resulted in no stations being found and a reported signal strength
(in Kaffeine) of 45% to 48%. I dismantled the system and reconnected it in
an upstairs room where the distance from the aerial distribution amplifier
is only about 3 to 4 metres. This increased the signal strength to 56% but I
could only get BBC stations.

I added a small UHF pre-amp between the wall socket and the lead to the TV
card. This increased the signal level by 9%. The signal to noise ratio
throughout was reported as 0% which seems a bit odd. The result though was
to just add another couple of BBC stations.

My television in a downstairs room seemed to get everything going but
unfortunately did not give priority to the highest signals, leading to two
hours of shuffling channels about and still needs treatment.

It seems that this exercise has well and truly left me behind!

Are you using autoscan or the scanfile.dvb entry for your transmitter?

I just discovered that the scanfile.dvb with the latest kaffeine is
hopelessly out of date because it is pre-DSO frequencies and parameters
for every UKofGB&NI transmitter.

So either use autoscan or download w_scan and use that to find the stations.

And anyways, w_scan is more "sensitive" to finding signals and locking on
to them than the kaffeine autoscan.

I ran a pre-compiled version of w-scan but it stopped with this:

FATAL: Your DVB driver doesnt support DVB API v5. Please upgrade.

So? Compile from source and then complain if it does not work.

Sounds like good advice but I have hit a dependancy error. So the drama
continues.

Thanks for your help

I would guess that the problem is you need to install a "dev"
package to provide the necessary header files in order to
compile the package.

I do not have direct experience with PC Linux OS but
presumably your are using yum or equivalent.

From the error given by running configure can you
work out the name of the needed library and then
install the needed development package with yum?

It will not compile because of a missing dvb-api that needs to be version
5.3 or better. Not available (yet) on the pre-release version of PClos that
I am using. I cannot find the source on the www either!

To get dvb-api 5.3 you need a Linux kernel 3.0, which needs a very
recent distribution. PClos 64-bit has a 3.3 kernel available, and there is
one in 32-bit testing.

Well, I installed the 3.2.15-pclos1 64-bit kernel but got the same message
as before. The kernel headers matching the kernel ae installed so fo the
moment I am a a loss.

I also managed to lose all sound! Kind of reminds me of the 'good' old days!

Unfortunately there are two sets of header files. One is provided by the
kernel headers package and is installed at /usr/src/kernel-devel-x.y.z,
the other comes from the glibc-headers-devel package and installs at
/usr/include/linux/dvb. While there is a kernel headers package for the
3.2 kernel, the glibc package is still for 2.6.38. If you are feeling
lucky you could try overwriting the glibc files with the ones from the
kernel headers.

I now recall why I gave up on the 64-bit PClos distribution and decided
on Mageia2 when it comes out...
