    SVCD is MPEG-2, ie DVD quality video on a CD. VCD is MPEG-1, desktop quality. Here is a good place to read some info:

    SVCD is better than VCD in all regards except for the fact that it requires about double the CDs of a VCD.

    SVCD doesn't work on many DVD players simply because manufacturers disable the read of the SVCD disc header; There are work arounds for it, you can rewrite the SVCD header with a VCD header and it plays alright.

    I use VCD

    #1 My DVD player wont read SVCDs

    #2 SVCD takes about 10 times longer to render than VCD

    Read above.

    #2 is also <b>very</b> much exaggerated.

    Have any of you tried the new variable bit *gasp* real media?? From what I have read/seen it rivals xvid. I believe the extention is RMVB.

    I don't see it going anywhere any time soon.

    I continue to envision XViD + AC3 audio in a matroska container the pinnacle of high-compression/high quality. I can see DiVX + AC3 in a matroska container taking over in the DVD market, although I would like to see XViD.

    Are there any good conversion programs to these formats?

    Which formats?

    Several were mentioned.

    RMVB (I assume that is real player), I am curious about Xvid+AC3, what is that?

    XViD is an MPEG4 compression algorithm, similar to DiVX. However XViD has considerably finer control over the quality and size of the video, whereas I view DiVX as the n00b's XViD.

    XViD files look better at smaller sizes than DiVX.

    AC3 is dolby digital audio, 2 or 5.1 channels, ~384kbps.

    Xvid is a compression format (like MPEG2 and DivX) and AC3 is Dolby Digital Encoded multi channel audio.

    TMPGEnc is a highly useful program, but for guides check out Thraxs' guides on the SM front page.
