Converting Hulu High Quaility FLV's - complete failure?

I have tried everything, but I always end up with A/V sync issues. the ones in question are the naruto epps. Try the high quality epp 26 for example.

I have tried several outputs in RMC and RC with no luck. Either it wont convert it at all, or it will convert it with massive sync issues.

I know the FLV's use H.264 for vid and AAC (quicktime) for the audio. Is there any free app out there that can let me manually (or automaticly perfered) to sync these together?
