If the 50i video file carries 50 individual fields which indeed contain individual steps of motion then you definitely should use the 50i file for DVD creation.
If you don't, you would throw away 50% of motion which you otherwise would have been able to put on DVD no problem.
So, check the 50i file for interlacing. If there's no interlacing then it's just the flag saying it's interlaced and the video contained within is actually 25p anyway. However, in that case there's pretty much no difference between the two files, so just grab the 50i.

However, I hightly suggest not to simply dump the ProRes file on CCE and expect it to make a great MPEG2 for DVD out of that.
CCE is a good encoder, no question. But it's an encoder – it's not particularly good at all the other things (most important here: scaling!) that need to be done prior to encoding.

Better use AviSynth for that.
