This is my exact upgrade path:

1. From Mythbuntu 8.04 and MythTV 0.20 to Mythbuntu 10.04 and MythTV 0.23
to
- Here all worked fine and I even noticed slight improvement in tuning and
LiveTV quality

2. From MythTV 0.23 to MythTV 0.24 (Mythbuntu 10.04)
- Here the tuning brakes

3. From MythTV 0.24 to MythTV 0.25 (Mythbuntu 10.04)
- Same
