Okay, I see. Then another suggestion. There are two types of Canon camcorders - Vixia (US/Japan) and Legria (Europe).
The difference between them is tricky: Legria supports 50i and 25p while Vixia supports 60i, 30p and 24p (!). The hardware in the camcorders is identical, so it's only the firmware that's different. Moreover, the firmware update on Canon website is also unified - it's the same file for both Legria and Vixia. The question is: is it possible to trick Legria camera (that doesn't have 24p mode) to think it's Vixia, and thus update the firmware of Legria camera to get 24p?
