Ripping DVDs is illegal where I live, so that's not a motivator in my case.

I do use 64-bit OSes for server applications, I'm wondering how specifically 
it might help the core Myth operations.

Obviously transcodes could be faster, but is anything else helped? 

I suppose I could ask the same question about multiple cores, obviously they 
help Myth to an extent, but would you be better off getting a faster single 
core or a dual-core chip?

Of course I usually try to get the fastest and the most cores I can afford.

On a 32-bit combined FE/BE I rarely hit swap with 1GB of RAM, which causes me 
to think 4GB or more would be a waste of money and power.

I think putting money into faster disk I/O might be a better place to put my 
money. That seems to be the limiting factor I what I can do.
