>> I had a perfectly working mythTV DVB-C (Germany) installation until

>> I figured out that, when recording something on this channel,
>> recording works fine in the sense that the video data is recorded.
>> The corresponding .mpg file stored on disk seems to be ok and plays
>> perfectly when I manually play it with mplayer (also, it doesn't
>> produce any errors, warnings or other unusual output when playing
>> it with mplayer). BUT: mythTV can't play this recording! The
>> preview icons both in mythfrontend and mythweb are just black (when
>> they're created while displaying them the first time, the
>> mythbackend process does something which causes load for several
>> minutes but doesn't result in any debug output or a thumbnail
>> icon). When trying to play the recording I just get a black screen
>> and mythfrontend keeps printing "NVP: Prebuffer wait timed out 10
>> times." -- just repeatedly this line, nothing more compared to the
>> usual output. (When deinterlacing is disabled, mythfrontend stays
>> reactive and playback can be cancelled using ESC; when
>> deinterlacing is enabled however, I've to kill mythfrontend.)
>>
>> I just can't get the clue what's going on here. Old recordings from
>> this channel reproducibly play and new ones don't. All other
>> channels still work. I verified that the VID and service ID of that
>> channel did not change. I also contacted the TV network and asked
>> if they changed anything in the stream format or the stream
>> headers. But they say that they didn't change anything lately.
>>
>> BTW: I'm running mythTV 0.21.0+fixes16838-0ubuntu3.1 on Ubuntu 8.04.
