yup, you could just be stupid! lol
Seriously, ChickenMan's tuts are pretty straight forward.
All you would have to do is load your mpeg file into TMPGEnc and provided your mpeg was set to the proper settings when you captured it (352x240 NTSC 29.97fps or if film 23.xx & your audo/layer-2 at 44100hz 224bits** or if PAL 352x288 25fps the rest the same), then you can just load it into the mpeg tools section & cut it to the right length of time to fit on each CD following CM tut.
If not, then you would have to process it in TMPGEnc from the first panel by loading it & then picking the right template for your VCD mpg file output.
Capturing with your capture card is only recommended for TV shows or VHS tapes. If you have a DVD-ROM drive, then best to use smartripper & store it on your HDD & then use either DVD2AVI (then loading it in tmpgenc to convert to proper vcd mpeg) or use flaskmpeg. This method will give you about 30% better result than doing your DVDs through your capture card 90% of the time. The other 10% of the time, you will get a 10% better quality result lol, so still better anyway you look at it.
Have a thorough read at the tutorials, cause otherwise you wouldn't be using your capture card for your DVDs (unless you have no DVD-ROM drive).
Good luck, & post any questions you need answered. That's what the forum is for.
(damn this was long)
