After testing of similar products now this box. As many others write, it is again with the drivers so'ne thing ... Under WinXP some frequencies are locked, pitch, if you just look for these stations. The hardware provides a good picture. For the software that I am very unhappy: 1. After the start of a recording can be no longer change (for example lengthen). I suspect that large parts of the program or anything written in processor code. Which of course leads that Windows and WinTV not work well together. I wanted this box with the program from Terratec (information joyful and better to overlook). But that probably will not give it. 2. After taste etlichem recordings fold reasonably. But when I record, I have to expect that 5-10% of the shots are empty: there is a file with the title of the recording, but it has 0 or bit is canceled during recording. 3. For I consider unacceptable the update of program information. If a program information is no longer correct, it may take more than an hour before the correct program information appears - and then only if you all the time receives the appropriate channels. That falls to especially in Phoenix and ZDF Info, often at short notice to change the programs. And you have every station whose program information you want to save, individually select and let stand for a while. There is no automatic update of all gemarkerten stations. In my (standalone) SAT receiver takes the update of all stations a few minutes, and he keeps programs up to 4 weeks in advance. WinTV program keeps information up to a week. This is very poor. Pity!
