I didn't think that was possible.   ;)

You almost definitely won't see any benefit above 6000kbps (you'll hit 
the limit of the electronics before the limit of the bitrate), but 
probably won't see much (if any) benefit above 4500kbps.  Make sure you 
leave good headroom in the max, also (at least 1/3 more than average 
bitrate, i.e. 6000/8000 or 4500/6000).  I've been using 2200 as average 
and the quality was good (not great) on my 27" NTSC TV, but it's 
definitely not that^H^H^H^Hat all good on my 67" 1080p TV...  ;)

4500kbps will probably give you about 2-2.25GiB/hr, and 6000kpbs will 
probably give you about 2.6-3Gib/hr including audio
