OK..sorry for the delay...

I have compared various formats on CloneDVDMobile and I did a comparison with Media Converter .99 from the DL site here.

I have found that CloneDVDMobile output is much faster, smaller and smoother than Media Converter. My only comment would be is that I hope CloneDVDMobile support the 770 directly soon!! The best format I found is still the D600 (low resolution). But, I find it a little grainy. Typical size is about 220 mb. on a standard movie. The conversion is literally under 40 minutes. And, it doesn't swallow all your system resources. The picture movement is very smooth. While I found MC .99 was choppy when there was a lot of action.

I think I am going to stick with CloneDVDMobile...

Update: Forgot to add the critical difference that may be a factor for you...CloneDVDMobile currently converts DVD's only. MC obviously does AVI. If you are going to convert retail DVD's ..you will need AnyDVD most likely as well.
