1. It supports (also according to the manual) only FAT32 formatted media, which bedeudet in any case limited to 4 GiB large files (more can FAT32 does not provide). I do not expect necessarily a NTFS support, but exFAT or ext-FS would I think as far as possible been.
2. The channel surfing could be a little faster. It's okay, but not as fast as some competitors. (I am referring to the analogue tuner, I can via DVB-T and DVB-C not comment)
3. At the beginning you will be extremely easy to use through the installation, including a new image setup in which you want to define different images "better" half of the picture. However, this resulted in the end to a very bad picture (maybe I have but also the image halves only to carelessly compared ... :)). In the end I simply "course" is selected the default and everything was chic!
Conclusion: 4 stars due to the small flaw ... had initially considered due to poor file system support to be awarded 3 stars.
