I wrote a couple of days ago about an mpg that was giving my DVD player fits when I tried to burn it to a VCD. I finally got it to work, but it required reencoding the entire mpg, which was a little time consuming and reduced the quality of the vid, not greatly but visibly. Now working with a second mpg from the same series, vcdimager reports:
---- INFO: scanning mpeg segment item #0 for scanpoints... ++ WARN: mpeg stream will be padded on the fly -- hope that's ok for you! ++ WARN: mpeg scan: pack header code (0x000001ba) expected, but 0x00000000 found (buflen = 2324) ++ WARN: bad packet at packet #15877 (stream byte offset 32533760) -- remaining 418452228 bytes of stream will be ignored ++ WARN: autopadding requires to insert additional 4364388 zero bytes into MPEG stream (due to 15813 unaligned packets of 15877 total) INFO: scanning mpeg sequence item #0 for scanpoints... ++ WARN: file `videocd.bin' exist already, will get overwritten! ++ WARN: file `videocd.cue' exist already, will get overwritten!

Can anyone offer a diagnosis (or an educated guess) about what is wrong with these mpgs. I know virtually nothing about the format of an mpg stream, so this may be poppycock, but it seems to me that the frames are actually ok (since the vid will play on my PC) but something about the way they're structured into a stream is screwed up. That being said, is there anyway to reassemble the mpg so it'll play nice without the lossiness of a complete reencode. I tried demuxing and remuxing with the last vid, and it didn't help. Any suggestions or pointers to info on diagnosing and fixing mpeg problems would be appreciated.
