RTV audio is mp2 which is compatible if you use audio copy. The problem is RTV mpeg2 has to be cleaned up before doing anything else with it. You will notice if you transfer RTV mpeg2 to Tivo it will play but none of the trick functions will work. The key is you need to run the mpeg2 from RTV through VideoRedo QuickStream fix (which you can do in kmttg) to clean it up before doing anything else with it. I just tried a 30 min medium quality RTV 50xx recording (800MB): * Original recording transferred to Tivo - trick functions didn't work. Attempting to transcode to any other format results in a/v sync issues. * Ran recording through VRD QS Fix - trick functions worked fine now when playing on S3. * Encoded the QS fix mpeg2 using ff_ps3 profile (H.264 video + AAC audio). Result was a 570MB file which pushes without transcoding needed to S3 Tivos and plays back fine and with proper a/v sync. NOTE: Unless you are looking for some space savings you are better off leaving them as mpeg2 run through VRD QS Fix instead of degrading quality by re-encoding.
