Hi, I have several questions, so I am not sure which forum to place this in, so I hope general is ok.

I'll get to the point. I want to burn my movie files that are in avi format to CD. I want to burn to SVCD format. I've been to www.vcdhelp.com and this site and the net for info (there's much out there), too much in fact that I dunno which is better that others.

Well I have been using TMPGEnc to encode to SVCD format. I have made 4 coasters so far and figure I try to get some help before making more coasters. Visually it is great, but I am having problems with the audio. When finished encoding, it plays fine on my computer both visual and audio. But after I burn it to disc (with Nero) and play it in my dvd player and watch on tv, the audio volume is low at quiet parts (ie. when characters are just speaking) and the audio is normal, loudness-wise, when say there are loud sounds such as explosions and street noise. I thought it may be TMPGEnc's audio encoding, since some sites have said it isn't for audio encoding, so I tried the tooLAME and used it as an external tool. But when using the tooLAME the mpg that came out wouldn't play. I would be able to scan to scenes/parts of the movie but it wouldn't play. I have tried converting the avi audio to a separate file and encode differently, but still got the same thing, the audio volume fluctuated.

Now, would this be a problem with my dvd player? or how I encoded it? or is it supposed to be like this? Again, when I play it on my computer it seems fine, although when I seek to another part of the movie the audio gets out of sync with the video, but when I burn it to disc it seems fine.

Can anyone help?

Also, an aside question, the SVCD template for TMPCEnc, has 1:1 VGA as the source aspect ratio under that Advanced tab settings. I find that with this I get a "stretched" look vertically, in other words the vertical resolution is wrong I think, so I set it to 16:9 525 lines NTSC. My question is if I keep it at 1:1, will my dvd player stretch it out horizontally when I burn it to disc, even though it plays "squished" on my computer? And would this be why I'm getting the audio problems? The original avi file looks to be widescreen by the way.

I'll explain what I did:
I'm trying to convert Rush Hour 2, an avi file in widescreen 576x240 resolution with the audio at 48KHz 2 channels. I've converted it to mpg with just TMPCEnc, and with tooLAME, as well as converting the audio to a wav file. There are the 3 coasters. I thought it was the frequency, so I tried another movie. Shanghai Noon, with 44KHz audio frequency. I got the same audio problem, the volume was too quiet at "quiet dialogue" scenes. This is coaster #4. Note the audio playback on my computer is perfectly fine, no volume fluctuations, but only after I burn it to disc and play it in my dvd player and watch it on TV does the audio sound messed.

So, could some help me out and tell me what I'm doing wrong or advise me on what to do that might help? I'm new to this.

Thanks for the help in advanced and sorry for the really long post.

When you burnt the SVCD did your burning app give an error (non-standard??)?

Nope, I used Nero 5.5 and it burnt fine, first time around it messed up because I had too big a file, seems some bitrate calculators are off, but I ran the simulation and it burnt fine. No errors.
