The one HDV machine I've seen with a description that might indicate some sort of correction that other players can't do would be the BR-HD50U:

The auto correction feature they describe as follows:
JVC has developed an auto error correction system that operates on a frame-by-frame basis to ensure accurate error compensation during playback. After optimally calibrating the playback RF waveform with a pre-filter circuit, the VCO (voltage control oscillator) control voltage is changed so that the data reading clock phase is shifted to the position where the error rate is lowest. The result is accurate, consistent suppression of block noise and reliable, professional-standard performance at all times
I have access to a variety of pro players, so if you have a tape that you can send me that doesn't play in anything you've tried, I can try it in what I've got and let you know if any of it works.
