No, the loss is at an internal converter, before standalone writes signal to HD or a DVD disc. The video part is not a big problem, at least when a low and average quality broadcast is blew up to a higher bitrate. Visual degradation is hardly visible - usually video is not as sharp as the source. Many standalone recorders, however, cannot capture pure 16:9 aspect ratio, making it 4:3.

PVR and DVB cards are directly connected to antenna/tuner, not to TV (signal). They work something like downloading a zip file from Internet, they catch transport stream which may not only contain video and multiple audio but also subtitles, electronic program guide, text info etc.

Not always. LPCM signal is broadcast by analog terrestrial TV only. All TV channels on satellite and terrestrial DVB use MP2 and/or AC3 compression. HD TV may use Advance Audio Compression format.
