RE: PCTV 520e - DVB-C not working
Hi, I have problem getting the PCTV 520e to work with DVB-C on Linux. The video output stream is full of defects. drxk: SCU_RESULT_INVPAR while sending cmd 0x0203 with params is printed to the dmesg log when scanning and watching DVB-C channels. I have no problems scanning and watching DVB-T. On Windows 7, both DVB-T and DVB-C works fine. So I guess its not an hardware problem or the quality of the tv signal. I have tried the drivers that came with kernel 3.3.4 and the latest media drivers built from source. The dvb-demod-drxk-pctv.fw firmware file is downloaded with the get_dvb_firmware script and copied to /lib/firmware. I can't figure out what the problem is. Has anyone got PCTV 520e with DVB-C to work on Linux? I have attached some log outputs below. You will need attenuator. I suspect it is LNA or some AGC :/ But guess what how many times I tried to found out the reason... Feel free to hack DRX-K driver. Problem found. I was LNA which is always enabled. LNA is connected to the demod GPIO. I will disable it since it since it is now over gaining strong signals. Great! I will be happy to test the solution. Is there a patch available?
