is there a reason to rip both 5.1 AND 2.0 audio tracks?

Hey guys, really hoping someone can clarify this, thanks in advance.
Whenever I use DVD Shrink, in order to get good picture quality, I usually strip out the commentary tracks, and other language tracks to cut down on total space. But I usually always keep both the 2.0 track and the 5.1 track, my reasoning being I just may end up watching this movie with 5 speakers and 1 subwoofer, and all other times on a standard dolby surround sound system (tv or pc). What I don't know is, is there even a reason to bother ripping 2.0? If you "play" 5.1 through a 2.0 only capable system, it's obviously NOT going to be 5.1. But is there some advantage to choosing 2.0 (what I have) as opposed to simply always choosing whatever the highest audio quality is? Does choosing 2.0 sound better than me playing 5.1 through my 2.0 capable only system?
You could tell me it's always best to pick whatever my current configuration of my system is, but is there a reason? If not, does that mean I could always choose whatever the highest audio quality settings are available, for example 7.1, and it would by default cover the umbrella of all settings UNDER that. (e.g. Someone with 5 speakers can just choose 7.1, knowing they would still get the 100% same audio quality as they would had they properly chosen 5.1 to match what they have).
Sorry if this was long and confusing, the reason I'm being so detailed this time is because I actually tried on two occasions to get this answer clarified on both experts-exchange and hardwareanalysis forums, and people couldn't answer me.
Thanks very much.
2.0--->2.0 = 5.1--->2.0 ?

Most systems can downmix 5.1 to 2 channel so I recommend keeping the 5.1, also typically the 2 channel tracks are reserved for your menu/special features/director's commentary etc.

Exactly what LOCO said.
I just want to let you know my experiences. I encode a LOT. Re-author DVDs. And I only keep the 5.1 sound track, and I haven't had any issue with sound, no matter what I played it on. Even my father's old equipment. So, maybe that will give you more data to work with.

My ancient Dansai isn't keen on 5.1 so I have a listen to see if the 2.0 only has directors commentary or is the proper soundtrack. If it's the real one i just rip that... but I'm usually ripping to avi anyway so I'm more interested in filesize than anything else.
Sometimes I find that the 5.1 sound on say a live music dvd sounds a little thin compared to the straight stereo mix when you rip it as audio only. Anybody else noticed that? Could it be a phase thing. This is where we could do with some input from Wilkes.. our digital sound guru.

That is the same way I operate.

Only problem is I don't think he ever comes by the DVD Shrink forum.

I guess a major thing I'm trying to figure out is, if keeping ONLY the highest audio setting doesn't have a difference in sound you hear, WHY do they even include the option of a lesser sound quality? When even have a 2.0 option in the audio menu of a dvd if you're gonna hear 2.0 ANYWAY by no matter what audio option you pick (assuming you have a 2.0 tv).

The option is there assuming you are playing back from the original source and your system should pick up what would be the default audio track. My logic is if I know my system will play 5.1 or downmix to 2 channel then I'll delete the rest and keep only the 5.1. It's just how I do it, but you are welcome to keep whichever, or both, if you want...honestly it isn't saving that much room for compression. BTW, the audio cannot be compressed so you are just stealing room by removing the audio so you won't have to compress the video as much resulting in better quality.

Ok, I think it's clear now, I'll just always keep whatever the highest audio track is, and delete the rest.

Glad we could help...I didn't really answer the question though. I suppose it's because not all system are capable of downmixing so the different tracks are there for you to choose from. I would think most modern systems would downmix with no problems, but I don't really keep up with them a whole lot. I do know that my new Sony receiver upconverts all sources to 1080i though :P
