Media Center Slipstreaming Help

[SinCityZ]

For starter I've successfully made both home and pro discs with no issues. For those discs I was using the latest nlite and update packs from ryanvm's forum (onepieces's post sp3 and also an AIO .NET framework if that matters).

I can't seem to get a working MCE disc however. The closest I got is a near up to date disc but I cannot get update rollup 2 to install, as it gives me an error every single time.

I've tried slipstreaming the rollup into a SP2 MCE disc, which works... but then I get an error trying to slipstream SP3 in.

If I slipstream SP3 first (of course replacing the 3 files from the SP2 disc), I then get an error while adding rollup 2.

I've added SP3, then media center 10, then tried rollup 2... same error.

I am at a complete loss here, does anyone know the correct order or anyway to get all the updates in a MCE disc?
