Hope you are making out ok with your mpegs. You may find if the discs have been finalized they will mount in your computer, otherwise they will only play from the camera.
I just completed some work from a Sony JCR-SR100 HDD camera that records mpeg2 to a HDD. I was able to import all the files to the desktop through USB. I used Streamclip 1.9.1 to convert them to DVCPRO50 but it was terrible. There was a luminance shift after every cut (from the original camera) and pans, tilts and any fast motion created jumps. I tried to stitch all the original clips in streamclip and burn a dvd but toast wouldn’t burn the file after only just repairing the tc breaks. Finally, since the camera played back everything well, rather than continuing to experiment I recorded the program onto a dsr11 through the composite out of the camera and got satisfactory results.
Streamclip has been very useful in the past but not this time. Sometimes the old “tape” to “tape” is still the best.
