Re-render in Vegas or le DVDA do it?

My 1 and 1/2 hour project rendered at 8.000Mbps default fit fine on an NTSC authored disk.
It is too large though for the PAL disk I need to make. I let DVDA recompress at 6.400 Mbps to get it to fit ( I reset the default) . Is this the best way to go or should I have re-rendered my project in Vegas at 6.400Mbps..is there a quality difference. Also is there a noticable difference between 8 and 6.4 Mbps? It is concert footage. Since I have no way of previewing the PAL render I'm hoping for the best. Is there a way to view a PAL DVDA project in a software player to check the quality?

Thanks
Bryan

Always re-render from the original material, when possible. Since your original material is in Vegas, not DVDA, this means in this instance that you need to re-encode to MPEG from Vegas.

If you re-render, using an MPEG file as the source (which is what will happen if you put the MPEG2 file into DVDA and then ask it to make it fit), will result in potentially significant degredation.

Thanks John, should I rerender source AVIs as MPEG_2 PAL in Vegas as my NTSC Mpeg 2 is fine for that render? Or rerender at the lower bitrate NTSC and let DVDA to the PAL conversion in Project Properties?
Thanks for the help

Also should I use the custom template screen VIDEO tab to lower the MAX bitrate to 6,400,000 ( the rate I need to fit the project) and should I then lower the AVERAGE bps which is now set to 6,000,000 or leave it there?
Thanks
