Can't fast forward movie

Some movie I tried to fast forward while playing will likely to return to the folder menu. It will show “this movie doesn’t support trick mode” Any helps?

The encode is bad.

Get out the original source disc and re-encode the file using a decent encoder.

Yup, as RoofingGuy stated, this indicate that the encode is bad, it is advisable to re-encode, there is not any workaround for this…
