    Conversion video loss? Which is better (TOD-->TS and TOD-

    I recently purchased a JVC 1080 HD camcorder that records video to the HDD as .TOD files. Now since I need to get these files to a format that I can work with for my software (in order to burn to BlueRay), I want to make sure that I have the best possible video with no loss of quality.

    At the bottom of this post, I have pasted the video info which I am confused about:
    #1. The info on an original .TOD file recorded.
    #2. Using Streamclip, I converted the .TOD to a headed MPG (not sure if this just changes the header or is a full transcode?)
    #3. Is a full MPG recode using Streamclip
    #4. Was created using VLC to only change the encapsulation of teh TOD --> MPG
    #5. Is the full .TS conversion using MpegStreamclip

    Ok so here are my questions:
    1. - It looks as if the .TS conversion creates an alomst exact file (Fames/Audio etc) for a perfect copy.
    2. - As I would rather work with MPG due to the nature of the programs that all support it however:
    Each one of the below MPG files whether converted ot just encapsulation change seems to have less video frames and audio???? Is this a loss in both video and Audio qualitiy from the original file, or is this just due to the inherent differences between TOD/TS and MPG? Can someone explain these differences?
    3. - What is the general consensus is TS better to work with or is MPG?

    Again, I want to get these files to Blueray so I do not want any qualityloss. Any help would be greatly appreciated.
    Thanks

    What blu-ray authoring tool are you going to use? You might not have to convert the mod to ts or mpg, it may be enough to just rename to mpg. I would try author the mod/mpg files to a blu-ray using nerovision or ulead dvd moviefactory. If it take several hours to convert/burn then it will reconvert = lose quality.
