How to fast forward and rewind on Toshiba regza

[hilo]

Hi All,

I just got a Toshiba Regza. I use PMS streaming movies from my PC to the TV.

If I dont apply any transcoding, I can "forward" and "rewind" the movie by the TV's remote swiftly.

But when apply the transcoding (for external subtitle of MKV movie), I can not forward and rewind. Only start - stop.

Could anyone pls tell me how to forward and rewind transcoded movie?

Many thanks!
