I recently encoded in gknot a video that has an ogg stream. The problem of the video is that it tends to pause or sometimes the music is stuttering. I encoded it by 700++bitrate, no qpel & bicubic sharp & 500 keyframes.I am using a pentium 3 400mhz. PLs tell me what's wrong with my encoding process??? btw I try to test the video @ 15% compreseblity check what does it really do???

May be you choosed a high resolution that your PII can't handle easily. Deactivating Bidirectional Encoding helps also lowering CPU charge.

-> lower the resolution (go for something below 512x...)
-> deactivate bidirectional encoding

This is usually a post-processing filter issue. Try turning OFF all options and see if that fixes it.

Start..Programs...DivX...DivX Codec...Decoder Configuration

I tried lowering the bitrate, cancelling the post processing the decoder settings but I didn't cancel the b-frames option & still it has the same problem. But its work fine if I play the vid in the divx playa!!! But since I wanted to stream it w/ ogg I have no choice but fine other solutions to this problem!!!

Maybe the CPU can't handle decoding the video AND the audio stream? How much CPU usage does Vorbis use anyway?

The problem is not w/ ogg but wmp because even w/o ogg it still pause or stutters!!!

Could you please check your cpu load during playback. If it's at 100% you should try encoding a clip without B-frames (it wouldn't surprise me one bit if B-frames are too much for a 400MHz cpu).
One of the reasons why The Playa doesn't stutter could be because it's using a different interface to play the video (Video for Windows while WMP uses DirectShow) and thus draws less cpu load.

@ kris2pe
I said lower the resolution, not the bitrate. The bitrate hasn't much impact on playback (it has to be very very high -over 8000 kbps- to *may be* cause problems for the hard disc to follow!)

As every body says, the problem is not GKnot. The problem is your procesor. Since DivX5 the CPU load for the playback has increase very mutch. You have to turn off all the features in the DivX filter o even use ffdshow (whith the postprocesing turned off). You can use too a ligth player, like BSPlayer. I've noticed in a PIII450 that some films (whith 'higth' resolution) canīt be displayed property whith the WMP6.4 but the playback is perfect with BSPlayer.
