Ok, have chopped out a lot....but you should get the idea. I need to call several EXE's in turn from a worker thread...but need to get each ones output.

[code] strTemp = (string)FileNamesToBurn[i];

// If its an AVI then we need to convert to MPEG
if (strTemp.EndsWith("avi") == true)
{
// Convert the AVI to MPG
strTemp = strTemp.Substring(0, (strTemp.Length - 3));
strTemp = strTemp + "mpg";

ConvertProcess.StartInfo.FileName = BurnerFilesPath + "ffmpeg.exe";
ConvertProcess.StartInfo.Arguments = "-y -i \"" + FilePathsToBurn[i] + "\" -target pal-dvd \"" + strTempFolder + "\\" + strTemp + "\"";
ConvertProcess.Start();

ConvertProcess.OutputDataReceived += new System.Diagnostics.DataReceivedEventHandler(processOutputHandler);
ConvertProcess.BeginOutputReadLine();

//while (ConvertProcess.HasExited == false)
// ConvertProcess.BeginOutputReadLine();

//ConvertProcess.WaitForExit();

FileNamesToBurn[i] = strTemp;
FilePathsToBurn[i] = strTempFolder + "\\" + strTemp;
}

if (strTemp.EndsWith("dvr-ms") == true)
{
// Then we need to convert the file to MPG
//ConvertDvrMs() // To Do
}

// if (strTemp.EndsWith("mpg") == true)
else
{
// Split the MPG into sepearate audio and video parts
ConvertProcess.StartInfo.FileName = BurnerFilesPath + "mpgtx.exe";
ConvertProcess.StartInfo.Arguments = "-f -d \"" + FilePathsToBurn[i] + "\" -b \"" + strTempFolder + "\\" + FileNamesToBurn[i] + "\" ";
ConvertProcess.Start();
ConvertProcess.WaitForExit();

// Merge them back together again but with "DVD" required bits
ConvertProcess.StartInfo.FileName = BurnerFilesPath + "mplex.exe";
ConvertProcess.StartInfo.Arguments = "-f 8 -S 0 -M -V -o \"" + strTempFolder + "\\" + FileNamesToBurn[i] + "\" \"" + strTempFolder + "\\" + FileNamesToBurn[i] + "-0.m2v\" \"" + strTempFolder + "\\" + FileNamesToBurn[i] + "-0.mp2 \"";
ConvertProcess.Start();
ConvertProcess.WaitForExit();
}

// Make the DVD files using Config.xml
ConvertProcess.StartInfo.FileName = BurnerFilesPath + "dvdauthor.exe";
ConvertProcess.StartInfo.Arguments = "-o " + strTempFolder + "\\DVD_Image -x " + strTempFolder + "\\Config.xml";
ConvertProcess.Start();
ConvertProcess.WaitForExit();

ConvertProcess.StartInfo.FileName = BurnerFilesPath + "dvdauthor.exe";
ConvertProcess.StartInfo.Arguments = "-o " + strTempFolder + "\\DVD_Image -T";
ConvertProcess.Start();
ConvertProcess.WaitForExit();
