Premiere Pro doesn't seam to like MPEG for editing. and I don't have a firewire capible capture device to transfer my Cable DVR recordings to PC. The need to import a Pinnicle USB710 device but can capture as DV. But for all the early transfers I made I used DVD quality MPEG2 5.1 encodings to HDD. I now want to clip out extra footage like commercials and lead in and outs. What is the best software to convert these files over without loosing any quality for better use in Adobe Premiere Pro 2.0?
