This post surprises me for two reasons. First, you were helped with this in 2009 (see your own posts). Second, your initial statement is false: BIAB made considerable improvements in the last two versions to how endings work and sound; this is one of the better recent changes to the program.

Since you have "another recording program" you could use Drag & Drop to take your song there, and adjust the ending to taste. You could also set that other program to record and then just playback your BIAB file; this will work unless both are set to ASIO drivers, in which case you should set BIAB to MME.

Are you using BIAB 2011?

To get a long fade, have you double-checked that you have the checkbox checked for Use 4 bar endings with RealTracks in the RealTracks preferences?

Are you up to date on the RealTracks, including the Holds and Shots file from last July?

Have you placed a hold (three dots) on your last chord, and then entered a rested chord (has to be different than the held chord) well after you want the last sound?

The heart of your question seems to be on rendering in BIAB, correct? If that delay parameter does not work as expected, try a Return to Factory Settings to make sure BIAB is working correctly.
