All aboard for a moderate price

To make it short: Who his own called the predecessor of S2, ie the TechniStar S1 and thus is fully satisfied, for there is no reason to switch. Apart from detailed changes in design, in the optics of the display and in the firmware me is so far still nothing relevant noticed what the S2 so clearly distinguished from S1 that it is worthwhile to take money in hand. However, if you had problems with the S1, or as a Technisat newcomers pushes only on the S2, can be accessed safely. I had at present, the receiver for 102 - purchased directly from Amazon, shortly after it had been lowered even further drastically on cybermonday. Even the 102 - are a selling point. The second, very important for me argument for the S2 is its running stability: During the S1 has booted irregular (even with the latest, each available firmware versions), the S2 is fully stable from the beginning. And who uses the Receiver to USB recording with a connected hard drive, appreciate this stability.

The operating menu still works as you would expect from its HD and non-HD predecessors, but there are a small pitfall:

Recorded programs could be in all (I know) Technisat firmware versions previously on the "Menu" -> "Music / Pictures / Manage Movies" - "edit their own recordings"> and start a final OK to the desired program. This no longer works when S2; the receiver returns only after OK back to the currently running TV program.

Instead, the "Nav Menu" is on the blue "Fast Forward" button -> "Movies / DVR" display. Next, we go through the "My shots - DVR". So stehts but also in the manual.
Who has multiple hard drives for recording the TS streams in use, should be ensured that each individual had been already registered at least 1x the receiver.

Of course, 2.5 "-USB3.0 plates are not an obstacle without a separate power supply for the receiver.

Let's see whether the S2 remains convinced by the stability described.

Addendum on 04:01:13:
Meanwhile, the S2 has yet been fired 2x. Once he gave up when playing a recording, which he had previously recorded himself.
The other times (yesterday) was particularly violent. It crashes and starts up again, showing the TV picture, but no sound. Even by changing to another station (or a recorded program on its USB port), he is not to move to the reproduction of the sound. Complete shutdown of the S2 and shutdown of the TV set also useless.
Only after the Philips TV has also been taken completely from the 220V power supply, there was sound for picture. Conclusion: The crash of the S2 had torn the HDMI connection to the TV set behind him, which had to be re-initialised after a complete turn off the TV set.
Thus, the S2 has far reached the susceptibility of the S1 (with me); the just described (really brutal) failure of S1 has, however, never made.
