Blocking and non-tradable recordings

1. My approach
I was looking for a new dual tuner Freeview HD recorder with hard disk. My choice was on the SAMSUNG BD-F8900 from Amazon which is blocked after a few hours. Furthermore, this model has practically no real export function of the recordings, I refer him to get a refund. My choice was then focused on the comparable LG HR939D.

2. Amazon Service
Amazon loyal customer, I literally trapped by the almost systematic lack of technical description from Amazon. After careful research on the internet, I think I have found the product that would suit me (export function uncapped for obscure reasons) with the LG HR939D. I ordered it in a very serious competitor Amazon at a price 25% lower.

3. Major defects observed
- Device quite bulky,
- Non-intuitive Remote Control,
- Presentation of simplicity really missing menus,
- Export function of virtually nonexistent records: no copy possible from the internal hard drive, no direct recording to NTFS formatted USB key or external hard drive (HD recordings over an hour)
- Minimalist paper user manual.

Note: the device comes to being locked in a few hours (cited problem in other reviews) my observations are limited. FYI, I have experience in this area of ​​4 previous digital TV recorders.
