Which DVDR for my application

I have read thru the post and it seems that I am at a loss, dvdr seem to have come a long way and I am not familiar with the lingo. I currently have dtv hdtv dvr and in another room a htpc running mce 2005. I was looking for the best way to archive my shows from the dvr's to the dvdr. I heard that there are dvdr that all can be accomplished by a push of a button. But do any of them allow you to pick the point to start recording and end recording? What about just recording a section of the recording and not the whole thing? Any suggestions for a good one around $200 - thank you...
