I've already watched this before ordering, so I knew what I was getting. For the price of a regular season, you get three episodes, that in my opinion where not very good. But what Red Dwarf collection is complete without Season 9 and Season 10. "Red Dwarf Back to Earth" is considered season 9. Do not expect any deep belly laughs like you get from the other seasons, but still expect to be entertained.
One nice feature about the blu-ray is you can either play these as episodes or as a full length movie. If you are ripping the blu-ray so you can play on Linux, android, or such, be prepared for a bit of a pain. Like several other BBC blu-ray releases the encoding is VC-1, 1080i. I could not find a linux program that could rip the blu-ray without sever macro blocking, and of the six different windows programs I tried only one produced acceptable results. But the blu-rays play perfectly on my blu-ray player, which is more than I can say for some of the other BBC blu-rays I have purchased.
The individual episodes are simply stereo (DVD) quality audio. But the director's cut movie version has full 5.1 DTS audio.
