Anyone have similar problem to mine?

I am trying to decode Divx movie myself using EOVideo. The output file is fine after converting using PC to view. However, when I view on Th-55 with MMPlayer, the player always complain Video Bitrate too high and stop playing. I tried using 216kps, 192kps..so problem..the only one it works is 64kps..but 64 is toooooo low..you can see the pictures at all but just sqares...

anyone successfully encode their divx and watched it on MMPlayer? I don't understand why 216 is too high.. Image Converter use 216kps for STandard mode and it plays no problem.

Hope someone can give me some insight.

thanks

***********Update **********************

Finally I have given up of MMPlayer.. Why? I have re-encoded an MPEG movie using TMPGEnc and trimmed it down to the right size (320x240).. played on Movie Player as well as MMPlayer.. I find Movie Player really play the movie smoothly... the output from MMPlayer is horrible.. so, I guess I wouldn't bother to spend time on MMPlayer.. unless ppl here can tell me something good about it.

BTW, anyone like me tried to play movies from both players? do you have similar experience? I wonder if it is because the "adjustable" processor speed of Th-55.. would it because Th-55 give full power to Movie Player but not MMPlayer?

Softech,

Hi. I really don't think that any third party movie player can come close to the built-in Clie movie player. I assume that this is because only the Clie player can make full use of the handheld engine's specific video-processing chip.

I spent a few hours yesterday playing with SmartMovie (which uses the Xvid for Palm codec) and MMPlayer, and came up with much the same results as you did. I was attempting to play a clip encoded using a 320 x 240 video at 15fps and 195Kbps (audio 18Kb at 22,000Hz).

Like you, I found that the only videos that would play were so pixelated and had such bad macroblocks that it wasn't watchable. I did get one to play OK by knocking the sound down to 8Kbps at 11,000Hz, but the sound quality was so bad that it was also not watchable.

I have read on the MMPlayer forums that others are using the software succesfully on the TH55, but can only assume that: 1) they have very different standards than I do; and 2) they are not using full-screen landscape.

However, remaining curious, I also went to the MMplayer download section and got a few of their sample videos. Their high-quality clip (Beastie Boys Sabatoge video, labeled as suitable for the T3) is just gibberish and noise on the screen for the few seconds it plays before the warning messages pop up. On the other hand, their lower-quality video sample (I downloaded a ZZtop video) plays with no problem and the sound is good, but at 192Kbps it is completely unwatchable.

DivX takes a lot of processing power to decode, and even effects a desktops performance noticeably, so I think it is just beyond the TH55's capabilities. I assume that you, like myself, have played with Kinoma an dteal movie, and have also realized that despite the good quality of the resultign files, the encoding process iks just too unstable.

What we REALLY need is someone who has the knowledge to put together an MQV codec or encoder plugin. However, I assume that this is a very big and complex job, or someone would have done it already.
