final cut pro 7: sequence settings

We just began editing in Final Cut Pro 7 and we want to make sure we have the proper sequence settings. We filmed on a Panasonic HDC TM-90 and we put the sequence preset settings to: Apple ProRes 422 (HQ) 1920x1080 60i 48 kHz because those are the settings we filmed in. However, when we drag a clip into the timeline a warning pops up stating "This clip does not match this sequence's settings or any of your sequence presents." We're worried that Final Cut is incorrect because we feel confident that we shot all our footage w/ these settings. If we say "No" to this pop-up, will we lose any quality?

Is it possible that somewhere between shooting the footage and importing it onto a hard drive using file converting software that our footage did, in fact, change from its original settings?

Any input on sequence settings in Final Cut would be helpful and appreciated.
