After more testing today, I found the following: With my SV 8000, with mpeg2 files, I can join them and edit cleanly and then playback via pc with just about any player w/o seams (stutter or loss of sync) where the files were joined.With the microHD, with mpeg4 files, I can join them, but playback is not smooth and there are seams where the files were joined.Today, I recorded mpeg2 with the microHD, joined them, and found seams where the files were joined.The difference between the SV 8000 and microHD folders is with the SV 8000 there is 1 .ifo and 1 .idx file (both unnecessary for the joined .ts file) with the .ts files, whereas with the microHD there are multiple .dvr files (which appear necessary somehow for the joined .ts file) with the .ts files.
