Seriously though, not sure what problem you've got but from what I can work out it all started here:
http://wiki.jriver.com/index.php/TV_Time_Shifting_and_RecordingThe first 2 posts here pad out the info above:
http://yabb.jriver.com/interact/index.php?topic=83310.0For myself, I record TV to .ts via 2 HDHR3-DT's and it's not unusual to find some artefacts by way of folders that show up a mess of jt(whatever) files. As I understand it, these are files associated with time shifting. Once the show's over and you've got a complete .ts file, it's safe to blow those folders away.
Be aware that recording to .jtv is more efficient, .ts requires more processing power. The advantage of .ts is that it's a generic video format, whereas .jtv is proprietary to MC. I use .ts because it leaves me with a nice neat file that can be recognised and worked with a variety of off-the-shelf software for editing and tidy up.
