Commentary
The Ugric etymology of tidó is impossible, for reasons listed already in the UEW. UEW notes that the interdialectal vowel-correspondencies within Khanty are irregular, and also mentions that Hungarian tidó is restricted to dialects in Szeklerland. It is quite clear that Hungarian tidó cannot be regularly related to any of the Khanty words listed here. The Mansi word is attested only in the northern dialects, making it a possible Khanty loan.
An alternative explanation for the phonological developments within Ugric has been presented by Pystynen in a blog post. He reconstructs a derivative *tojə-ntV, but it is not quite clear how this would explain the phonology of the Ob-Ugric words, and it also remains unclear what exactly is the stem *tojə-.
Conclusion
The Ugric etymology should be rejected as phonologically impossible.
