I've been experimenting with Eye TV's export to Toast option (with 7 and 8). I've found a MPEG2 file, I encoded at the highest quality, (3.2 gigs for 90 minutes) with 18 chapter markers, takes 80 minutes to multiplex and the write to disk image on my MacBook Pro (on my G5, it took a few hours :blink: )
The same video, exported to a file, then brought into Toast (so it no longer has the eye tv chapters, and instead gets Toast's default 5 minute chapters) multiplexed and wrote in about 5-10 minutes--the standard time I'd expect (only tested on the MBP).
Another EyeTV video, only 30 minutes long, regular quality, and with only 6 chapter markings, has no noticible difference done in either of the two methods.
I don't know if this is an issue because of the quality, the # of markers, or the length, and whether the issue is on the eye tv or toast side, but it's a few additional data bits for you
