[QUOTE="geirgp, post: 346955, member: 85877"] Hi, After reading your reply I have tested MP using several different decoders including MPV and ffdshow without seeing much difference. I seems however that you might have given me a valuable clue in terms of looking into decoders. I have not managed to find out what the problem is but I have made the following observations: I experience the big video startup delay when: [LIST] [*]Tuning in a DVB-T signal (MPEG4, H.264 - only SD, no HD) [*]Tuning in Composite signal [*]Starting a recorded tv-show (recorded from DVB-T source, H.264?) [/LIST] Interresting thing is that the delay also applies to the recorded shows, i.e. not a tuner-delay problem. I do NOT have the same delay when I [LIST] [*]Start playing a high def video that I have downloaded from somewhere, eg. 720p x264. [*]Change to a different channel (without changing frequency) from the DVB-T source (provider multiplexes a heap of channel into the same frequency). [/LIST] When a channel is tuned in the UI also works perfect with very quick response for all types of functions including timeshifting, ff, rewind.. There is only this looong delay when I fist tune in the channel or start a recorded show. Again, when I use the media center software (iMEDIAN) that came with my HTPC case there is no such delay. Unfortunately that is the only good thing about that software too, so I am using MP despite this annoying delay because overall it is much better. Considering the tv delay issue seems to happen only to video from the tuner (both live and recorded) is it correct to assume that MP may have difficulties decoding this type of media? If so, does anyone have a clue where I might start troubleshooting? Thank you very much! Geir [/QUOTE]
