Managing screen output from PowerCLI cmdlets?

The output I get shown from running cmdlets in my script varies, sometimes there's quite a lot of info written to screen other times there's none, but I can't figure out why. What do I do to manage the output?

For example, my script does

Start-VM -VM $cbrvm -Confirm:$false

Which currently results in >30 lines of data being displayed:

PowerState              : PoweredOn
Version                 : v7
Description             : Provides services
Notes                   : Provides services
Guest                   : MY-ESX-VPX:
NumCpu                  : 2
MemoryMB                : 1024
HardDisks               : {Hard disk 1}

<etc.>

Yesterday this same script was NOT putting the data on the screen. I've made some changes since then but none to the Start-VM command and don't know what makes the difference.

Thanks
