My vitamin D is seriously low, to the point where I have to take prescription supplements. Is this true about the fish oil blocking? Can you provide a link to some information?

It's the vitamin A content in fish oils that blocks D absorption. Also be careful about taking vitamin A supplements when you're trying to get your D levels up.
"The only dietary source of vitamin D ranked higher than sardines and salmon is cod liver oil, whose vitamin A blocks absorption of some of its very high vitamin D content"

"A few weeks ago, the British Medical Journal published a remarkable paper, remarkable that it studied more than 500,000 subjects, remarkable that it had 56 (fifty-six) authors, remarkable that it confirmed low vitamin D levels obtained in the past are a risk factor for developing colon cancer in the future. However, the most remarkable part of the paper is that the 46 scientists minimized the true significance of their own research. They found that vitamin A, even in relatively low amounts, appears to thwart vitamin D's association with reduced rates of colon cancer. [...] However, hidden on page eight is one sentence and a small table, which shows that the benefits of vitamin D are almost entirely negated in those with the highest vitamin A intake. And the retinol intake did not have to be that high in these older adults to begin to negate vitamin D's effects, about 3,000 IU/day. Remember, young autistic children often take 3,500 IU of retinol a day in their powdered multivitamins, which doesn't count any additional vitamin A given in high, single doses."
