Both in terms of underground quality, image and driver - warning of this "instrument"

First of all - the unit there were from LIDL, but named "Silvercrest USB Video Grabber".
Included is other than the USB adapter even a few cable (RCA, S-Video, USB extension, SCART adapter) and a software CD.
While the driver is no problem to install (via SETUP), but appear in the Device Manager only exactly one device, "ITE Video Capture Device". This device is only as the image source in a program later as "AF9035 Analog Capture Filter" selectable.
One program is the included CyberLink PowerDirector 7 - although totally outdated because there is now a version 13, but as far as it works. However, it is not very performant, but it jerky for example when shooting.
The image quality is also underground, not deinterlacing other settings are available, recording format is always MPEG2.

If you try to use any other software, the USB grabber is not detected from the recording device (eg. Windows Essentials 2012 Movie Maker).
In Windows 7 the mixer device is not displayed as a sound source.
Theoretically, you could also record the sound with another adapter cable via soundcard, but then sound and picture is slightly different times.

I warn so explicitly before this unit. There are no new drivers, with whom one could have possibly more success. The purchase would be just a waste of money.
Too bad that you can not be a NULL star.
