  1. Hello,

    My Philips DVP5140/12 chokes at the end of some XviD files. From what I can tell, the only common denominator is the VIDEO_MPEG4_BVOP value--the ones that play don't have it and the ones that fail, do.
    From what I read in another thread, there's no quick and easy way to get rid of BVOP; I have to re-encode. Is this true? If so, can I re-encode while preserving both quality and file size, or is the new file guaranteed to look worse than the original?
    I'm also reluctant to convert to DVD+R instead. The original files are about 2 GB... I think a resulting DVD wouldn't look as good.

    I'd really appreciate some help!

    2GB is a fairly large Xvid for a movie, so the bitrate is probably high enough to produce a reasonable DVD from. It is also probably high enough to withstand a single re-encode if you use a 2-pass encoding on it.

    The player shouldn't have any problems with B-VOP's and if it did, then it should effect the entire file, not just the end. Could be it is having problems if the file is over 2GB's.

    The bitrates are 1706 kbps and 1611 kbps, respectively (there's also a third file, but I'll just leave that one alone). Will converting to DVD look worse than the original AVI? Would it look better than re-encoding the XviD or worse? And as for re-encoding XviD to XviD, what settings should I use for the XviD encoder?

    I considered that and I chopped enough from the end (direct stream copy in VirtualDubMod) that Nero Burning ROM accepted the files in an ISO compilation. But the framerate still drops to a halt (and doesn't pick up). I also tried adding black frames at the end, hoping the framerate drop would occur in a part that I don't care about--no dice.
    So I guess there's a problem in a specific part of the video files? That's the only other explanation I can think of, since I tried about 5 different media, all which Nero verified successfully. I can also play other XviD files fine.

    There are other factors that will influence the quality when converting to DVD. These include the resolution of the source file, as well as the running time. If the resolution is low, then any flaws in the source will be exaggerated by the resizing required to get to DVD resolution.

    If you want to find out how it will look, use FitCD to create small avisynth script, use the Trim statement to isolate a few minutes worth - preferably high action or smoke and fog - and do a test encode at the correct bitrate.
