Gods, the horror.
Point the first, if the Internet is to be trusted then that player’s only video output is HDMI, so any SCART solution is going to involve some sort of hackish conversion. In lieu of knowing anything about your TV (does it, for example, have S-video or component connections?) then the best you’re going to get is an RGB signal. This is going to be DVD-quality at best, though I’d guess that on a TV devoid of HDMI it’s not capable of displaying much more anyway. Also, we’re looking at the digital-to-analogue conversion of an encrypted data source, so cheap cables are unlikely to work. A converter box that actually works will set you back something North of fifty quid.
Point the second, if you’re using the amp to watch TV using the TV tuner itself as the source, you’ll have to use either the optical digital input or the analogue inputs on the amp to receive that signal. Does your TV have either of these connections as outputs? The optical connection can transport true 5.1, but it’s a moot point here as standard definition Freeview will be Pro Logic at best anyway, and any stereo connection can carry this.
Point the third, that player has no further inputs, meaning that if you want to run anything else through the amp now or in the future such as a game console, Sky or some such, you’re knackered. If you’re only ever going to use it to watch films (or whatever streaming services it offers) then that’s fine, but if you’re going to use it as an amp for anything else you might want to consider the next model up which has a couple of HDMI inputs.
