Using a Slingbox with a Bell 5900 DVR

Okay,

The Bell 5900 PVR is not listed under the Bell section in the slingbox configuration menu. Here's how to make it work.

Select 'Echostar'
Select 'Other' (actually selecting Echostar might be completely irrelevant, you may be able to select "Other from any of the menus)
Select 'Code 8' and try turning the DVR on and off... it should work.
For leading zeros check '0'
Try changing a channel... this should work too.
Finish the rest of the setup, the remote won't look the same as the actual PVR remote, but it's working great for me so far.

[Update Oct 11, I returned the slingbox today, the slingplayer for mac just wasn't cutting it, too much audio lag... and high motion video (hockey games) looked it was dropping frames when panning from side to side. It was too distracting to use.]
