There will be a free plugin for Premiere Pro to add HDV support. This plugin is developed by my company CineForm and should be available in the near future (an NDA prevents me from disclosing details.) CineForm sells a higher performance, more feature rich, HDV accelerator, called Aspect HD which is available now (and works with all known HDV cameras.) See www.cineform.com for details.
