quick warping question

[celestial]

most of the time when I warp ableton will warp tracks fine, but I got 2 issues that I noticed sometimes happen:
1 - sometimes it won't recognize the track properly and it'll start it on a wrong measure
2 - it'll put a load of markers in a the track, and then when it plays it'll slow it down like crazy throughout those markers

I know it's probably something easy I overlooked but does anyone know a quick fix for those?

Don't trust in Live's own warping...you have to do it manually...

I have to agree, anything more than 2 or 4 bars seem to not work very well for me.
