Default Adding video time to match audio

I've got a home made video that is roughly 5:06 and the existing audio is undesirable. I want to replace the audio with a specific audio file that is roughly 5:13.5. Of course, I don't want to cut off the audio at 5:06. That's too easy. I want the entire audio. Therefore, I need to increase the video time to match the audio. In other words, I need to add roughly 7.5 seconds to the end of the video. I want to do this with a still frame. I'm pretty sure this is doable and probably fairly simple, but I'm having a little trouble figuring it out.

This is what I've done so far:
1. Demuxed (with PGCDemux) and remuxed (with Muxman) with the new audio. I realize I may need to remux again if I should have added the still frame beforehand.

2. I added a blank cell at the end of the remuxed video with PGCEdit. However, I can't seem to figure out how to increase the playback time of the blank cell to 7.5 seconds.

Finally, I know that once I've got the correct playback time of the added cell and my still frame, I will need to replace the blank cell with the still frame in VobBlanker.

Can someone please help?

You're almost there. You don't need blank cells or VobBlanker.

1. Demux - you'll have an m2v and audio fle.
2. With muxman, add the original m2v AND a BMP. Set the BMP's time to 7.5 seconds. Also in muxman, add the substituted audio stream.

This technique is similar to that "Save heaps of MBs" in my signature (except you don't need to cut anything).
