The HDR-FOX has three main files: ts, nts and hmt (plus a thumbnail). The ts file is the one that contains the actual recording. The FVP-4000T does not have a hmt file but has hjm file instead: see here. It is probably the hjm file that contains the synopsis information (this is embedded in the ts file too) so you may not see synopsis information for your transferred files. The HDR-FOX will play a standalone ts file but only with limited transport controls (no rewind and fast forward, but the skip forward and back buttons do work). It will not play a ts file if the corresponding nts file is present without the hmt. If you find that your transferred files do not play on th FVP-4000T, try playing the ts files without the nts and hmt file present.
