If that's 5gig in computer terms, you'll actually need to get down to 4.37gig in computer terms. 4.7gb is a base 10 representation of the size, so from the computers perspective you've only got 4.37gb available.

Anyway, you may need to do some experimentation to do this. Jetdv has avery nice newsletter, and one of the old issues has a bitrate chart (issue #7 I think), so go to: http://thetroxels.com/tts/ there's an index that will help find it.

Take the length of your project and find it on the table, that will tell you what average bitrate you need to use.

If your video has lots of fast action, you may have a bit of a problem, since those are what usually gets hit first. I'd probably try compressing a typical scene at the suggested bitrate and then kick it out to an RW to play back and see how it looks on TV. If it's not acceptable, you might be able to split it out - render other stuff at below the suggested bitrate, and then the problematic scenes at a higher bitrate, then use TMPGEnc's MPEG tools to connect the individual MPEGs together into the final movie.

Another option might be to try a 2 pass encoder. CCE Basic can do 2 passes and can be frame served by Satish's framserver. CCE Basic isn't very expensive. Encoders that do more than 2 passes usually start around $2,000, though they usually offer other features such as the ability to go in and select certain scenes for different treatment so you don't have to render individually and then merge together. (CCE SP for example).
