Supersound, but Smart Apps can completely forgotten man, USB problems

Find the complex itself is not bad, the sound is good and it will play almost all popular formats!
However, what bothers me for the price, the LG apparently not baked it gets functioning smartapps integrate, inter alia, YouTube today is important and that's what you can here completely forgotten, not charging, crashes repeatedly or plays only halfway. In the previous model, the APP has at least still halfway works. In addition, the 3 months suddenly films of hard drive or other USB storage media and bucking or the system hangs completely and only leaves off draw with plug! (Contact with LG is also pointless, more than you reset the device to factory settings or the hard drive is defective? You can hear where not that advise a more even return the plant to Amazon) I have followed and the plant at Amazon returned! I'll post 2 LG plant upgrade to a Sony system times.
MFG Michi
