Does the harddrive spin up (to refill the buffer) when the slowdown appears?
Skeith:
Its okay the problem has been resolved. It was an issue with TMPGenc. I encoded using WInFF and all is fine.

Hello
I'm getting some syncing problems on a video which works fine on my desktop but not on my iriver h340.
skipframes is enabled.
limit fps is on.
mencoder toxicity.mpg -of mpeg -oac lavc -lavcopts acodec=mp2:abitrate=96:vmax_b_frames=16:vb_strategy=2 -af resample=44100:0:0 -ovc lavc -lavcopts vcodec=mpeg2video:vbitrate=600 -vf scale=220:176,harddup -ofps 30 -o tox.mpg
I had it encoding at a lower fps but higher gave better results. Sorry about the video, was the smallest mpg I could find for testing :) There's a significant difference you can see if you compare desktop to iriver.

Thanks

The iriver h340 isn't capable of decoding 30fps in mpegplayer. According to the documentation:
http://www.rockbox.org/twiki/bin/view/Main/PluginMpegplayer
it can manage about 11fps full-screen at the moment.

I've reencoded at 24fps, although was getting this during the process:
Pos: 222.3s 5574f (99%) 11.53fps Trem: 0min 18mb A-V:0.050 [587:95]
24 is the lowest mencoder will allow and it's still a problem. Any other suggestions on how I can do this?
Thanks for your time.
