The device also comes with an analog input, but the analog part is not supported by the linux driver yet(?). The analog input provides composite and s-video connectors using an included adapter cable.
See the external product page for more information.
Support for the DVB-C and DVB-T part of the tuner has been added to kernel, and include since 3.4 in all stable kernel releases. 
Log from initialization on kernel 3.3.1 with latest linux media drivers built from source, and firmware extracted from Windows driver:

The DRX-K demodulator requires a firmware file that must be uploaded by the driver: dvb-demod-drxk-pctv.fw
This file can either be downloaded by the get_dvb_firmware script available in kernel source.
Alternatively, you can download the extracted firmware directly from this link
Target directory: /lib/firmware
The 520e uses a shared frontend for both DVB-T and DVB-C.
IR Remote Control
The remote control can be used with "inputlirc". During install from lirc, select in the dialog for receiver and transmitter in each case "None". A helpfull side is Configure_VRC-1100_remote_for_Ubuntu. "lirc" alone does not work with this device.
In the Windows software "TVCenter" (available from PCTVSystems), there is a option to disable the amplifier. This option is currently not available(?) in the linux driver. This might be the reason why the device has problems locking on some DVB-C frequencies .
Latest ACG (Automatic Gain Control) changes in the TDA18271 driver.
If w_scan doesn't find any channels you may want to try a slower timing using "-F -t3" parameters.
