Seen a lot of posts on this recently with the new TMPGEnc-2.59.47.155-Plus-EN
In the past I have recommended installing Power DVD 4, which supplies one of the 3 filters that TMPGEnc supports. If anyone is using this cyberlink filter with TMPGEnc 2.59 + and is not experiencing any problems, let us know !

Meanwhile, try the "Ligos" Mpeg 2 filter, Supplied with programs like Ulead Media Studio Pro (Demo), but can be used with TMPGEnc +. I have also heard its on KaZaA (What ever that is) as a stand alone. 8)

When used with TMPGEnc + Set with a higher priority when converting/editing/cutting/joining Mpeg 2 files.

TMPGEnc +
Options > Environmental setting > VFAPI Plug-in > Right click the MPEG 2 Decoder and select higher priority. Do this several times until its at the top.
