VanderL:Until this process is shown to really happen to the neutrino's coming from the Sun's core, I still consider there to be a problem

Direct Evidence for Neutrino Flavor Transformation from Neutral-Current Interactions in the Sudbury Neutrino Observatory, Q.R. Ahmad,
et al., Physical Review Letters 89(1): 011301, July 1, 2002.
This report shows that the total number of neutrinos observed coming from the sun is equal to the total number of neutrinos that is predicted by the standard theory of nuclear fusion. The fusion reactions inside the sun create only electron type neutrinos. The early experiments that first established the "solar neutrino problem" could detect only electron type neutrinos, and did detect about 1/3 of the expected number. The hypothesis that neutrinos have mass, and can therefore "oscillate" between states, and become non-electron neutrinos on their way to Earth, was one proposed explanation for this deficit in observed neutrinos. So the
Sudbury Neutrino Observatory set out to observe those non-electron neutrinos. It did observe them, and the totals all add up as they should, consistent with the hypothesis. If neutrino oscillation is not the correct explanation, then how else might one explain the fact that the total number of electron plus non-electron neutrinos, as obserbed at SNO, matches the total number of electron neutrinos that should be generated inside the sun by fusion processes?
First Results from KamLAND: Evidence for Reactor Antineutrino Disappearance, K. Eguchi,
et al., Physical Review Letters 90(2): 021802, January 17, 2003.
This report shows the results of antineutrino measurements, as a function of distance from a neutrino source, using the
Kamioka liquid Scintillator Anti-Neutrino Detector (KamLAND). They have observed a fall off in antineutrino counts, that is consistent with that expected by neutrino oscillation theory, as the antineutrinos they detect oscillate into other types. This is a terrestrial confirmation of the same basic process that also explains the SNO neutrino observations.
There is a considerable collection of references to papers for further study, and some web resources, on my
Solar Fusion & Neutrinos webpage, which I encourage you to follow, up.
If these results seem unsatisfactory to you, perhaps you can tell us what you need to see, more specifically, before you will be convinced that conventional scientists are at least on the right track.
