Do you think I should get a Panasonic DMR-HS2 or a dvd burnwer for the computer such as the Sony DRU-500A or the Pioneer AO5? If I get the burner for my computer, I would also get a tv tuner. Would this cause a decrease in quality from my TV cable? The TV tuner I would get would probably be the creative digital vcr. What are some positive and negative differences between a standalone and a pc burner?
