@loggio:
The ForTheRecord addon and the MediaPortal (TSReader) addon share the same code for reading the TV stream from the timeshift buffer files and stream it to XBMC. From my personal experience: SD channels on localhost are ok. Over the network via WLAN: most SD channels: ok, some show heavy stuttering. HD channels: some work, others show a garbled image and 100% CPU usage. All tested under XP and Windows 7 without DXVA.
My guess is that the TSReader code is not fast enough to handle HD channels in all cases. I've copied this code from MediaPortal itself, so in theory it should be able to read and process the data fast enough, because its working fine in MediaPortal. Key difference is that the playback method of the stream in XBMC and Mediaportal is completey different: internal ffmpeg v.s. external codec.
Another possible reason for a garbled image/stopped playback: switching from an SD to HD channel (using up/down). XBMC does not see the suddenly changed video stream format.
