I'm recording and video taping a recital soon, and I have to make both audio CDs and DVDs of the recital. I have separate audio (oktavas) from the camcorder. I'm worried about sample rates though, so here's my question:
I plan to record in 24-bit, 44100Hz. The 44100Hz is for the CD, however after the concert is done I will also master the audio with the video to make a DVD. Will I be able to align the music with the video and put this performance onto a DVD, which uses a 48000 Hz sample rate without any detriment to the audio quality (I have heard that if you don't record in 48000 then sometimes there are "clicks")?
I just read my original message, and it seems a bit convoluted. More simply put, if I have a recording with a 44.1KHz sample rate, and video with no audio, can I sync up both the audio and video and burn it onto a DVD?
I normally make two or three captures with the same outboard/tape playback settings if I have the feeling there will be a film, video, DVD involved.
That way, your covered without any extra sample rate/bit depth conversion, and it will always sound as good as it can!

Clicks may happen when you transfer and/ or playback with mismatched sampling rates .
You'll be just fine going from 44.1 to 48KHz as long as you use a decent SRC.
Voxengo's excellent R8Brain Pro is my SRC of choice.
I would use Minimum Phase mode instead of Linear Phase mode to reduce the chance of a nasty ringing artefact in the high upper mids (Min Phase is the equivalent of hardware DAC/ADC process, and there will be no artefacts at all).
You would do better to record at 48KHz and avoid SRC completely though, but the downside here is your sample libraries might well be at 44.1, meaning they get SRC'd on the fly in your DAW which is definitely the worse of the 2 options.
24/96 on DVD-Video is pointless, as it is optionally supported & stands a high chance of automatic SRC on the fly at output, and also has a (lesser) chance of truncation to 16-bits. All that is actually mandatory on DVD-Video disc is 16/48.
