Thank you for your message. On another computer, the video displays correctly. The problem is only on this computer. I bought this computer specifically for the cameras - the new Dell Vostro 460 / Intel i7-2600 / 8GB / 1TB (7200) / DVDRW / ATI 6670 1GB / W7 for 64-bit. I tried to install video codecs, the latest driver .. Nothing helped. I do not know where else he could be a problem. I need to make it work just on this computer ;( Any idea please? Thank you in advance for your help ..
