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.
regards
Antti
