Hi there, I´d like to share with you my recent experience with DVB-C cards and a Brazilian Provider. My first attempt to use a DVB-C was with a KNC1 card. I just had to download the latest source from dvb repository, compile and install. The card was identified, I could scan channels and watch TV. BUT some channels works very badly, as the card couldnt lock properly on a few transponders (309mhz and 321mhz). Running a czap on those channels shows that the card keep "locking" and loosing the lock. I thought that the problem could be something with my cabling, so I tried my card at a friend´s house with the same results. I also tried a attenuator, but without success too. On my second attempt I bought a twinhan CAB ci card. Card identified, but scan didnt worked. Some googleing later, I got it working by commenting the line 1360 in dst.c (!(state->dst_type == DST_TYPE_IS_CABLE) &&). To my surprise this card has NO problem locking on 309mhz and 321mhz channels. It seems to take a little longer to lock/changing channels compared to my twinhan DVB-S card (I´m comparing apples and oranges, right?), but so far it´s working ok. My third attempt was with a technisat cablestar HD2 card. I used the mantis repository to get the card working (is the mantis driver already merged with v4l-dvb?). Again, I can scan channels, but the card could not lock on those Transponders. In fact it also take a lot longer to lock on a channel, but after it got a lock, it works right. Since twinhan works fine, I supose that there´s no problem with my cable/splitter. Also, I supose that the chance of two disctinct broken tuners is low. A recent thread on TT-1501 shows that, if I understood it right, there´s a kind of table where a power level is set to each frequency range. Is it possible that my two cards didnt worked on those especif transporders because of this kind of setting? BTW, the two non working cards have a TDA10023 demodulator. I´m not a dev, but I would like to help to debug this. How can I help? p.s. posting to linux-media, as I was told that linux-dvb is deprecated. -- Christian Lyra POP-PR - RNP -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
