If none of these help, if you could set debug level to Major, and run a download first with Decrypted and then Default, and post the result, I'll see what I can find. Follow this app Developer website cTiVo overview cTiVo is a free Mac application to download shows from your TiVo (Roamio, Premiere, HD, S3 or S2 devices) and convert them to many popular formats and devices. It will download as fast as the TiVo will allow, and do no conversion whatsoever. Sort by Station, and you'll see any mixed channels. Each tested show will now have either - for MPEG2 or a (dark check) in the H.264 column. It's very quick per show, but it has to wait a minute in between to not upset the TiVo downloader, so it'll do 50-60 shows per hour. Then install MPlayer OSX Extended or VLC to view the downloaded movie. Hit Download (or Add to Queue), and let it run. It copies the show from the TiVo and does no conversion on it whatsoever. If not, if you're ok with using up a lot more hard drive space, you might select the 'Decrypted TiVo Show' format. Decrypted TiVo Show: This is also a Format for experts. Hmm, any chance cTiVo has changed from PS to TS underneath your tests? (If it detects an MP4 stream trying to be downloaded with PS (ie no video stream present, just an audio stream), then it auto-shifts to TS and tries again.) If you look in the log, you'll see the exact URL being sent, which will include the "&Format=video/x-tivo-mpeg-ts" if it's a TS transfer. Unlike Decrypted TiVo Show below, it converts the file format to MP4, so you can add subtitles, commercial skipping information, and other metadata inside the file. If you temporarily enable "Don't delete tmp files" in Adv Prefs and do a Default download, then you will see the bufferSHOWNAME.mpg file in your temporary directory, which should be exactly the file that is saved by Decrypted. If this were the case, you might try tivoLibre decoding in Adv Prefs, but that requires Java to be installed on your Mac. On the other hand, before that happens, the decryption process itself can definitely fail due to glitches, potentially skipping sections or truncating the file, but that would affect downloads in both Formats. It's difficult for Decrypted TiVo Show to get (or write) less data than Default, as the same flow is used in both cases, except that after receiving and decrypting the file, Default then calls ffmpeg (in a complex batch file process) on the file, and Decrypted just writes it to disk.
