If the software is up to date (or higher 6.13.24.820) function every 3 Tuner without problems. Even in our old house installation, through which we have very poor reception, there are no problems with image or sound. So no artifacts or even demolition of the signal.
The software is very easy and intuitive to use. Planned recordings even work from standby out without problems. The operation using the supplied remote control works very simply and in addition it is even possible with their help to control other software. WinAmp and WinDVD are just two of the preset software products that are supported.
Even the DVB-T receiving the included antenna is possible without me. Only within a space it can lead to problems, here you should then have recourse to an indoor antenna with amplifier.
Even if the bundled software is no good: 100% buy recommendation for this product :)
Tested on Windows XP, Windows Vista and Windows 7 are under 32bit and 64bit.
