Problems with Sizzle (audio and authoring)

[SilentBobCDN]

Ok, where to begin. I was following Galactica's guide for converting SVCD to DVD (ffmpeg, sizzle and toast) and my first problem came up when i was trying to add the converted-to-48khz .mp2 files to Sizzle. It kept saying that they werent .mp2. I got around this by using Sizzle 0.5b1 (not b2).

Next. I author the dvd, burn it, stick it in my player and i scan forward to make sure everything looks right. It cuts to the ToC menu at the end of what would be the first SVCD file. I havent found a way around this besides the following:

Third: To get around this, I re-muxed the three files and used MPEG2 Works (demo) to join the files together. I check the integrity of the movie, its fine. I demux this new 2gb-ish file and proceed to go about as normal in Sizzle. Everything is accepted, but the resulting .dmg file is only covers a third of the movie. This boggles my mind to no end. I tried it in both 0.1 and 0.5b1 and the same result.

Any help at all would be appreciated, even if it shows how much of a newbie I truly am.
