It seems alot of people, including myself, are having problems with vcd playback when played on their standalone DVD players. Personally i seem to have an abundance of macro blocks, short freezes and audio going in and out of synch.

At first i thought this may have been due to nero burning with not enough ram so i tried afew with only afew programs runing and burning at a slow speed (x4). this works for me when audio CDs do not urn correctly, but in this case it didnt help much.

after reading some posts i thought it might be due to the bitrate going abit over 1150 in TMPEG 2.

It finally workerd, I did a test with 1140 and it came out fine, when looking thru the encoding logs it seems that every now and again the encoder goes a little over 1150, it seems regular enough to cause the problem. That's the only reason I could think of for it not to work. Anyway, thanks for the help everyone. - Shabubu

I was hoping this would solve the problem, but when playing it the video was half off the screen and flickered heaps (yet there were no macro blocks, freezes, or audio problems). This seems to happen at bitrates below 1150 (ive tried 1140 and 1100).

Can anyone give any advice with these problems? I think perhaps my DVD player (Lenoxx 9000) may be only able to play VCDs at 1150 bps, if this is the case how do it stop the bit rate in TMPEG fluxuating? (ive selected fixed bitrate).

Any help is greatly appriciated.

I am having problems with playback of VCDs on an Aiwa DVD player. Nearly every one has a short skipping of the video somewhere. I use TMPG to encode the video and I remux and split it with BBMPEG. I use the VCD template for NTSC(FILM). I think I will try one in NTSC@29.97fps to see if it makes a difference. Also, why when you try to mux an M1V file encoded in TMPG with a MP2 from toolame do I get buffer underflows/overflows and timestamp errors? The resulting VCD plays very choppy and out of synch.

I personally don't use TMPEG to encode my movies, but I have a solution for you. I will upload my template and I use this all the time and it has never caused me errors. You bitrate is supposed to fluctuate. Use toolame (with SSRC for better quality results) for your audio encoding. This should create an MPEG file that is fully compatible to use with Nero, but nero has problems, so I suggets you use VCD easy (from Doom9's download page) and create a valid BIN image file for you to be able to burn. You can then use BIN to ISO Converter (http://www.megagames.com/console/cd/bin_to_iso_converter_v2.0.zip) to convert the BIN file it generates to ISO that you can burn with practically any cd burning application. This process should create a really good VCD that is very compatible.

It is a NTSC-VCD(film) template.

I used to have the exact same problems with my XWave 1000K standalone.:mad:

But this cured it :D

Check out this page for a statement on the muxing abilities of TMPGEnc http://www.vcdhelp.com/VCD2TK_TMPGEnc.htm

VCD Mux is part of the Phillips VCD 2.0 Toolkit, available here http://www.icdia.org/sw_pc/vcdtools.html

If you change the video bitrate to anything other than 1150 it'll result in a non-standard VCD, with probable trouble later on.

Hope it enlightens :)
