afaik dts is only possible with hardware decoder, others can be decoded with 
software. hmm.. what i know, a pentium 2 @ 333MHz class computer with linux 
2.4.18, a gfx card with some nice features like colorspace conv and scaling 
for example (dunno more, i'm more like a user :) which are afaik likely to be 
found on every modern card, and mplayer ofc i was able to play any dvdrip i 
could get my hands on, when with only mplayer actively running i had no 
framedrops..  ofc your soundcard drivers must be somewhat good too. 
framedrops only occured when the bitrate of videostream became higher than 
1500kbits or something, can't actually remember.

hmm, i just re-read your question, no, i wasn't able to play DVD with the 
computer above. :(

i haven't heard of opensource AC3 encoder.. though i haven't even searched, 
which you ofc can :)
