Supersize deals with the room the TiVo sets aside to record the stuff on the TeleWorld Paid Programming that it records in the middle of the night.
When it offers to show you a preview of some TV show or movie, that's where that footage came from.
We're only talking about 30 minutes of video, but apparently the TiVo sets aside a certain percentage of drive space for the Teleworld stuff, so if you increase the hard drive size, it'll set aside a lot more than it needs.
Supersize, in some way, keeps it from setting aside more than it would when using the original factory installed drive.
Your problem has nothing to do with Supersize.
What you need to do, at this point, is hook the 2TB back up to the PC with WinMFS on it (but not the original 160GB drive), open WinMFS, select the 2TB drive (should be under File, Select Drive).
Once it's selected, do File, mfsinfo
Look at the partition map.
You'll probably get something that corresponds to this--
Partition Maps

13 MFS MFS media region 2 171919990@64 ( 82.0G)
except that there will be a 14th partition called an Apple Free Partiton, and it'll be quite large.
(If you instead have a 14th AND 15th partition, an MFS application region 3 and MFS media region 3, or names similar, then we have a different situation on our hands than I think that we do, and you should ignore the rest of this post, look for something you can click on in the WinMFS options that will let you save the mfsinfo output as a .txt file, and come back and post all of that)
If you don't see any indication in all the mfsinfo stuff that anything's wrong, close it and click on File, mfsadd
You should get a box where you can tell it to go ahead and make a partition bigger than 1.2TB. Do so.
When that finishes, go back and click on
mfsinfo
again and make sure everything looks right and that you now have a 14th and 15th partition, filling up the drive.
