I am making a compilation of a load of video clips.

TMPGenc encodes them all great, Nero burns it to vcd great, but on playback on a standalone dvd player, some of them are great, one is "speeded up" and the other few are either a mass of coloured blocks (sound isnt too bad) or a blank screen ....

Any ideas how to sort the "bad" ones out, so they are all "viewable"?

Thanks!

So did they all play on the PC okay before burning to cdr ?

Yes, they played perfectly on the PC.

I did notice that when I started up TMPGenc, the ones that are NOT playing on my standalone dvd player were not 100% NTSC, they were 30 fps and in the encoding bit of TMPGenc, it said "1:1 VGA" or something. The GOP structure I did leave at 152, because 30 fps is closer to NTSC than PAL ....

Any ideas? Running the bad ones through GSpot come up with a whole load of "n.a."

TMPGenc does not do a good job of converting off spec frame rates back to standard unfortunately. For VCD, I'd suggest you have at look at the good old Panasonic MPEG Encoded, I think latest is 2.5.1. If the originals were AVI's, then try The FilmMachine though I've never tried it for VCD's. MainConcept is another worth looking at.

As for the mass of coloured blocks, thats simple the wrong codec being used or the original AVI was crap in the first place. Check them with DivFix or DivxRepair.

Get the latest GSPOT Beta version 2.5x, it works great and provides MPEG info as well as AVI.
