Again, are you sure it's a limitation? 
There was a big discussion about it and all developers agree that the 
ringbuffer is needed to implement stuff like pause, save what you just 
watched and so on.
So, if you think that this all can be done without a rungbuffer, try to 
convince one of the developpers.

I never use window so I never used pvr software under windows.  Is there 
windows software that works without a ringbuffer and is able to do all the 
fancy stuff mythtv can ?

Btw, what version of mythtv are you running?  If you are able, try 0.18 or the 
very latest 0.19.
