Beware - V8 does not support HD-DVD.
From what I have ready, V8 will coexist with V7, so you can keep V7 for HD-DVD playback. If you don't mind using two different players, one of which may no longer see updates.
If you go to the Cyberlink web site, you can view a page that compares versions of PowerDVD - including V7 and V8. However, you will find that the chart does not include PowerDVD Ultra V7 (PDU7). If you have PDU7, you may wish to dig a bit deeper before paying for the upgrade.
