audio problem...HELP!

[chickens]

Ok...I always like to convert my medias to vcd format. The problem is when I play the file in a VCD or DVD player, I can hear the sound like kind of cracking or lots of "sandy" sounds...but when I play the same file in the computer I never seem to hear those sound. I always use the wizard in TMPGEnc to convert my files to VCD format. Well not all of the file have the problem..only some.

One more thing, in TMPGEnc, when I replace the audio of a video with an .mp3 file.....and play it in VCD or DVD player...I will also face the same problem: sound cracking......is this all have to do with the bitrate of the audio?...because I notice that mostly of my .mp3 files are 128kbps......but the TMPGEnc wizard converts any media into 224kbps .. ..?!?!?

I really need help ..... Anyone who is good in video or audia stuff...pls pls pls help me...

Not sure about this but here goes...

If you are converting downloaded movies to VCD (you don't say) then the audio in these varie in encoding method and parameters used. Using the TmpGenc wizard for VCD, it will convert all the audio to 44.1khz sample rate. In some cases it will have to perform a sample rate conversion to achieve this and it is recognised amonst the Tmpgenc user community (and the author himself) that Tmpgenc does not always do this well. To solve this porblem the Tmpgenc author allows the users to specify their own sample rate converter, the one usually being reccomended being ssrc.exe. Use google to find this and incorporate it into TmpGenc using the Environmental setting/External tools options and give it a try.

Hope this helps
