I briefly tested the new CD Spin Doctor that came with Toast 9 and the filters seem work w/o distortion just like they used to. I haven't recorded or applied the filters and saved anything yet, but based on my short test at least the problem seems to have been solved with the upgrade.
That's kinda good, and kinda bad because I don't think a pay-for upgrade should be THE solution to a bug. But, the 'bug' seemed to be caused by a change in either Quicktime or Leopard (or a combination of both), so I guess we can't expect the programmers to have a crystal ball when it comes to operating system or Quicktime changes. I would think they at least owe those using Toast 8 a patch to fix it however, but where's their profit motive for doing so? (Other than the obvious good-will they would generate instead of alienating their user base to the point they might not continue buying Roxio upgrades.)
Roxio must not believe in much of a beta-test cycle. There are so many kewl things in the new Toast 9, some of which are totally broken and useless (on my system, anyway). For example, editing a .TiVo file is a total fiasco for many Mac users. If you trim out the commercials (using a very very coarse and non-precise means of marking in and out points), the AUDIO doesn't get trimmed. So the saved result is a video file that is missing the video of a commercial (good), but the audio continues on as if it had never been cut out (bad). This makes the edited results totally useless, and a colossal waste of their users' time. I can't believe they'd let it out the door being that broken, so there must be something fairly common that most users have installed that is fouling up the process and giving results that they didn't expect or anticipate when they released it. Here's hoping enough people initiate an incident report (or whatever they call it) so this issue will get their full attention.
