Hi All,
I'm toying with a dvb-t300 that appears to be almost there...
I tried 2.6.17, but couldn't get the dvb-t300 nor the 0.7 series ivtv
drivers, for the --normally working well-- hauppage pvr-250mce, to work
at all.
Reverted to 2.6.16, no luck with the stock kernel drivers => installed
v4l-dvb-a3a095225de1. & 0.6.3 ivtv => looking better..... but unable to
get mythtv to successfully use the new dvbt-300 card.
I was unable to get anything out of the analogue or dvb of the dvbt-300,
despite all devices being created as you'd like them to.
I suspect tuner type issues may be at hand...?
Nothing from the analogue tuner which is listed in saa7134-cards.c as a
TD1316; on the card is also a TDA9886TS that loads with a TDA9887 tuner.
After creating the relevant transports for AU and scanning in mythtv, no
lock ony any channel, despite signal strength >= 58%
Import of channel info from zap did not assist still unable to get lock
on dvb.
The correct tuner appears to be detected ... on card lists as a
TDA10046A & dmesg shows TDA10046H frontend.
Are there any module parameters to play with here for the tuner modules
e.g. a PAL setting?
I've had a dig around the relevant c files but can't see anything obvious.
Better still, can anyone tell me that they have a dvbt-300 behaving and
what it took?
Cheers,
Lew
A bit more detail below for anyone interested in picking through the
heap below in search of something to fit the picture together.

I'm a bit concerned about the duplication with the tda9887, wondering if
the ivtv & std drivers play well together?
The kernel log doesn't look bad, though: you should not load the
tveeprom module. It is for the BT chips, not for saa713x.
Second: there still is an issue with the module load order: if the
tuner module is loaded (by a script) before saa7134, the tuner of
the compro card is not detected.
But dvb-t is independent of this. I see that the channel decoder
comes up. There are 2 possibe reasons why the channel decoder
might not lock:
- The parameters like FEC in your config file are wrong. Some drivers
ignore them and force to auto - the tda10046 does not.
- You live in a country where the transmitters operate off the channel
center frequency, like Britain and France. Currently you need to correct
this by hand in the config file.
So i would recommend to validate your channels.conf file.
