    I have a panasonic Rv32, and it never plays anything good. Infact the video playback is extrememly laggy, and the audio sucks too. Ive heard people say that if could be because of the bitrate, which in one of the cases is <2500. So i was thinking that maybe if i could reduce the bitrate down to 2000 or so then id get a good playback.
    This is SVCD.

    I wanna try something similar with some of my vcds also though.

    Thanks for your cooperation.

    Tmpgenc doesnt read my SVCD/mpeg2 file.
    "cannot be read or is unsupported"

    I got this from some other post. So i downloaded Mpeg2 plugin, and copied the .vpf file to tmpg folder, and ran mpcfg or sumthing. But now it tmpgenc just freezes when i try to open the file.

    Here is a little trick i have learned along the way it sometimes works. Open your Windows Media Player. Play the movie in windows media player - click file at menu - rewind movie to beginning - click on save media as - save the movie to another directory, after doing this try running this mpg through tmpgenc. I have found that this has worked for me before

    Also in order for tmpgenc to accept the mpeg2 sometimes you have to adjust the environmental settings (you will find this at options in tmpgenc menu), vfapi plugin, increase the priority settings for the mpeg2 video plugein, this will sometimes let you encode a video that TMPGEnc wont accept at first.


    Good luck Ibonic

    You can increase the plug-in priority, in TMPGEnc, by clicking option - environmental setting and then click the vfapi plug-in tab. Right click on whatever you want to make higher and click higher priority!

    However in this case, the m2v plug-in, it doesnt freeze it just takes a very long time to open the video stream, leave it sit for a while! However, with the m2v plug-in, the audio source will most likely not load!

    So what can i do for my audio?
    Ill try that.
    Isnt there some other solution to getting my Panasonic to play any cds that burn, not just SVCD's. I tried downloading some mpeg1 files and burning them onto a cd(vcd), but it wont play those properly either. It played them better than SVCD but still was very very bad.
    I have Panasonic RV32.

    It could be just the media you are using!

    For the audio, demultiplex the audio stream and load it as your audio source, however this could cause out of sync problems so setting up tooLame as your external mp2 encoder would be a good idea!

    I think i figured out a way to solve the vcd issue. I took a bad file, and encoded that on a bitrate of 920 from 1150, and now it works like a charm. Now, if i only i could get tmpgenc to load the file, for my svcd.
    In laymans term what do u mean dela. :)

    Thanks dela.
    I really appreciate the help.
    How can one person contain so MUCH knowledge?
    Dang, a living Encyclopedia. Way to go!

    Btw. I found another tutorial for converting SVCD to VCD. Let me know what u think of it?

    Thats a good tutorial. See if u can link that.
    Works very nicely! :)
    The only problem is tmpgenc taking 6-8 hours for a typical american movie. And 10-14 hours for a typical indian movie.

    At the end of the video, last 10-15 mins. It flickers every now and then, freezes for about 2 seconds. Its still tolerable, and enjoyable. But i was hoping for a perfect video just like its played on the computer and at my friends house, and especially after 10-12 hours of encoding. Is there any way?
    Im encoding the file @ a bitrate of 917. What do u think?
    Im not sure if the problem is the bitrate or something else. I have a panasonic rv32. When i burn them onto a cd without burning them it doesnt work on my dvd player, but works like a charm on my friends Mintek 2110. After encoding it works on my dvd but the flickering is there, not as significant but still present.
