It takes, as I was told on demand at LG, a DVB-C tuner. The devices, which are currently mainly in the market have, but all only DVB-T tuner, so they convert the analog program only back to digital. LG wrote me that they currently have no DVD recorder with DVB-C tuner on offer.
Thus, you always have a quality loss with this, but also the other DVD recorders with DVD recordings. A real shame.
The LG RH 398 H, I then sent back because my 2 year old DVD recorder from Aldi funnily enough the same, in addition even VPS, which I have not found in this device.
And that Aldi device (Medion) also responded to the remote control of the LG device, the menus, everything was the same, so I still suspect that Aldi has shopped with LG.
