AVC/h264 MPEG2-TS recordings from DVB-T goes out of sync

[lif]

Hello!

Our provider broadcasts DVB-T only in h264 with mpa audio. GBPVR 1.2.13 is recording shows successfully to transport stream. But is when playback these recordings. Sometimes longer recordings (ca. over 30min) goes audio and video out of sync about up to 5++ seconds, also rewind and ffwd produces sometimes out of sync and sometimes not. No difference when playing recording through GBPVR UI or WMP11 UI, still behaves the same. Is it GBPVR problem when recording shows or is it demuxer or codec bugs? Tried CyberLink h264 codecs, CoreAVC, Nero digital, ffdshow. The best result is with Elecard AVC codecs (but its trial and will expire soon). CPU power, network bandwidth and video performance is not the issue. Any suggestions?

.ts files are recorded byte-for-byte as the data arrives, with no manipulation of the data, so I can only assume the problem is a playback problem. It is most likely either related to the combination of audio/video decoders, or the audio renderer (recommand "system default"), or the demux filter. For playback in WMP, which TS source filter are you using? (a common one is Haali Media Splitter)
