I've been thinking about this already. Unfortunately, GUI is one thing I hate, so for now, I use my laptop as a terminal to my freevo box, and adjust the EDL with a text editor. > How reliable is your system?

It has been working correctly at 99% (probably even more) when generating the EDL while recording, and even closer to 100% when generating the EDL after the recording. > You also mentioned in the past issues with the EDL frames being off > slightly, what is the repercusions of this in terms of cutting permanent > video out?

What happened is, that when mencoder drops frames (because I'm watching a DVD at the same time and the processor is overloaded) the EDL was inaccurate by several frames. This should be fixed in the dev version (haven't fully tested yet). But this never happens if you run the filter once the recording is over (actually, for safety, when I plan to really cut the video before archiving it to CD, I always re-run the filter, manually, after the recording has ended). Then, with recordings stored into AVIs, I use transcode's aviindex to find the I frames closest to my EDL's values and adjust the EDL, and then call transcode to actually cut the video. For non-AVI video (i.e. DVB), I'm not sure how to proceed yet. Here are the possibilities I see: - implement the EDL mechanism in mencoder also, in order to use mencoder to convert to XviD using the EDL to cut the ads - implement a TS parser in transcode to use transcode's cut plugin, - remux the TS to a PS, re-run the filter (because of PTS changes during the remux), and then transcode the PS/Mpeg to AVI/XviD using transcode's cut plugin, - convert the raw TS/Mpeg to AVI/XviD with mencoder, then use the filter, and then use transcode to cut the AVI. Converting the TS to PS (and fixing the PTS at the same time so that there is no PTS reset in the PS) while recording the DVB stream is an option also. For some reason, it sounds more of a cheat than the previous options, even though it would make my life much easier (we have a PS already, the EDL can be made easily, and transcode can be used for cutting while transcoding, and mplayer can use the EDL to jump the ads while watching, after a tiny bit of tweaking in the seek function of the PS demuxer, to make it more accurate). If I want to keep the MPEG as is, I might try to hack into GOPchop to make it a command-line tool, and use it to edit the MPEG without transcoding. But GOPchop understands only PS, not TS, so remuxing the TS would be needed too. Anyway, I don't have a DVD burner yet, so this is for the future. What is higher priority for me now is to get the filtering work while recording with mencoder to AVI (that's mostly working) and work with DVB recoring, also in real time. For the second part, I need the seek in mplayer to work accurately for TS which contain a PTS reset. I'm working on it, but slowly. Editing the video will come after that (I don't archive very much of what I am recording, I usually record just so that I can watch the show later, when I have time.
