From what you are saying it’s playing perfectly. I think you maybe just don’t like LD.

From what you are saying it’s playing perfectly. I think you maybe just don’t like LD. I guess what I mean is I wish I bought a machine that can play these discs. I feel like I'm missing out by having discs with audio that I can't access. I think I will take a look at my amp next and work out how I convert tracks into the surround that will use my rear speakers. There's a lot of different sound symbols on the back of discs and it's a little bewildering. I'm loving my actual player even though the picture isn't as good as blu-ray or 4k. There's a cosiness to the films which I really like. I just want to ensure I'm watching films in the best possible way and with this player it doesn't seem like I can do that.

Buy only Dolby Surround 4.0 or 4.1 stereo or mono discs.
If your goal with LD is surround then get ready for some fun times ahead. That's why I only use a 2 channel setup, my music and movies always sound great with no issues, just buy a really, really good pair of speakers. I've been told that DTS will pass through my optical lead which is why I've ordered Jurassic Park. What is 4.0? Two front speakers and two back?

If you have a modern receiver, DTS should work fine through your optical output. "4.0" is misleading. It refers to 2.0 stereo tracks on disc that in production were downmixed from 4.0 sources (left, center, right, rear) in a such a way that a receiver can roughly split it up into the original 4.0 mix on the fly and map it to your speakers appropriately. On the database this will typically be labelled "Dolby Surround." As far as cabling is concerned they are simple stereo tracks. Quote: I think I will take a look at my amp next and work out how I convert tracks into the surround that will use my rear speakers. Yes, get to know your amp better. Any modern amp should have modes that use all speakers even when playing back two-channel sound. The best thing to do is read, read, read. Read your amp's manual, read your player's manual.

This is all being inflated way out of proportion...
LD is a latently stereo format. The 5.1 stuff was added on 15 years after the start of the format and is not essential to enjoying LD. Don’t FIXATE on it like this, it barely matters. It’s a cool hack and that’s about it, like Enhanced audio CDs with QuickTime videos on them. Worry about it later. Your player can’t do AC-3 anyway so you’re hundreds of dollars and multiple broken eBay players away from the Dolby Digital LD experience. Learn up on what you have already before buying more stuff. More stuff will only bring more confusion.
When LD launched it had two tracks of analog sound, much like a tape. You could use stereo sound or two different mono tracks (commentary, isolated score, languages, etc). Later on they added CD quality digital sound into the format sacrificing nothing. So if you have later discs and later players you have two different stereo tracks to chose from. Depending on what disc you have you may want to listen to stereo analog, stereo Digital, or just the Left or Right from one of them. This is why you are able to select them that way. All of this is in the manual for any LD player.
Any two channel stereo (tapes, records, Gamecube games) can contain a matrixed four channel system. Dolby Pro Logic is the name used for the multiple systems used to unfold “2.0” into four channel Dolby Stereo/Dolby Surround. I hesitate to use terms like “4.0” because it was never used in period literature and can only cause confusion. Also, it *isn’t* 4.0 because it isn’t discrete, only the master was. The LD version is 2.0 with available separation via matrixing, which isn’t the same and doesn’t sound the same.
Your amp will do Pro Logic because newer versions are built into the specs of newer formats for the purposes of auto down mixing and reconstitution (cable TV). Therefore you can get Dolby Surround (earlier analog version of Dolby Digital) from probably every movie you have on LD that had it in the theater using the stuff you have right now, from either the analog or Digital stereo tracks. Star Wars, for example. If you have any Star Wars LD, your LD player, and any Dolby certified Surround receiver you have all you need for Dolby Surround. The vast VAST majority of LD owners in the 90s only ever experienced LD home theater this way. The 5.1 stuff was borderline millionaire grade gear. A niche of a niche. A sub basement in the basement of LD.
It’s your stuff, read the manuals and learn how to use it. You can do it. When you’ve come to know what you already have then when you go to learn about 5.1 you likely won’t have any questions, it will all make sense.

I've got stuff playing via Dolby Surround on my amp now and it sounds better than when I first set things up. It's a shame I can't access the AC3 tracks, but maybe that's something for another day. I'll watch the videos that were recommended today. The look interesting.

I would still recommend getting another player if you decide you really want to stick it out. And if you do that, minus well seek out an AC3-RF capable player if you want to eventually get into AC3. Modding your current player for AC3 is also an option but you'll need to understand what needs to be done to make that work.

My 2 cents. I second signofzeta's general sentiments. There's no reason to fixate on being AC3 capable. It's not that big of a deal.
I went almost two decades coveting AC3-RF players and demodulators. When I finally got them, I almost felt like I wasted my money. It is a cool feature for films where the surround effects are really well done, but it isn't going to change your life. For many movies (like basically anything not an action or space flick), I'd rather listen to the stereo PCM tracks because the sound quality is better.
AC3 is a lossy compression codec similar to MP3 (though slightly better) and as such, introduces artifacts to the audio that can sometimes be heard. Sometimes it's pretty noticeable, and depending on the film, it can be worth the trade-off in pure audio quality or not. That isn't to say it sounds bad... it doesn't. But sometimes you can tell.
As far as discrete digital surround goes, DTS discs are far superior. The quality is better, and there's no expensive demodulator required. Unfortunately, they're less common and considerably more expensive.
tl;dr: IMO, if you come across a player that can output AC3-RF and can find a demodulator at a reasonable price, definitely consider it. But don't be too concerned about it and feel like you're missing something essential to the LD experience. You're simply not.
