This thread seems pretty dead, but assassda if you happen to see this - I'm having the same problem as crezwell above. I created a disc with songs and videos from RB1. Everything went perfectly, following your tutorial. The songs imported fine, the names of the tracks were changed properly, and I had no problem replacing the videos. However, on about half of the songs, the notes don't cut out when you miss them. Songs like "Cherub Rock" and "Sabotage" work 100%, the notes cut out when you miss - but on songs like "I Think I'm Paranoid" and "Should I Stay Or Should I Go" the vocals are muted, and the notes don't cut out when you miss.
I am but a humble noob
when it comes to RB customs, and I'm certainly no programmer - but I've read that this problem has to do with the mixing of channels in the .mogg file for each song. And someone posted on SH that you can't just copy and paste the .mogg when making customs - you actually have to use a program like Audacity to mix the channels and make sure you have a total of 9 for Wii. Do you know if this is true - and maybe some tracks just match up by luck? And does your track replacer copy and paste that info? Any insight, or links to channel mixing tuts, would be appreciated. Great work, by the way.
