I bought an external hard drive in order to record the Technisat TechniStar S 1+ television broadcasts can. The receiver detects the hard drive without any problem (they must lt. "Technisat" FAT 32 formatted to be). The recording and playback is easy and problem-free. Also connect the external hard drive to your PC to burn the movie on Nero Vision to a DVD to him then to look back on the DVD player on TV to succeed without problems. Here is true in my opinion absolutely to the price-performance ratio. Top-commodity at a top price.
