CCE SP 2.5 Question

[Booooom]

Hello all,
I am using DVD2SVCD with CCE SP 2.5.
1. When I use CBR and Check the Create Vaf File checkbox, does that mean I actually doing 2pass CBR. Does 2.5 has 2pass CBR at all and what are 2pass CBR advantages

2. Is there any need at all for checking the Vaf file while encoding with CBR (in terms of better encoding).

Thanks.

1. No and no. I can't imagine a multipass CBR encode providing any advantages, although the later CCE-SP 2.67 versions do offer it.

2. No.
