[mythtv-users] For playback only?

[Blake]

Is it possible--and is it wise--to setup a mythTV box in pieces?

For example, I'm waiting on my capture card. Can I set up my box to just  
playback recorded video until I'm ready to install the card?

Later I might want to add other components...

Anyone have experience putting a system together in pieces. (Deliberately,  
I mean.<s> Sounds like lotsa folks do it on accident.)
