Help with timeshifting configuration

[Zorg]

Hi,

I have two cards in my Windows XP SP3,
-Skystar2 PCI
-Win Nova T 500 dual tdt (so maybe three cards)

I'm running the last Media Portal and TV Server version and also the last svn version.
The skystar2 is connected to three lnb-satellites and in total I have 70 channels (including the TDT channels)

The thing is now and then, I don't know why, when I change to a different channel I can't see it and next to the name of the channel appears (timeshifting), between brackets. For instance ARD (timeshifting), I change to another one and the same, France 2 (timeshifting), but I can't see them. I have to restart the PC.

In tv server general configuration I left the default configuration in timeshifting, because I had no idea: Minimum: 6 files. Maximum 20.

May be the problem is there, I don't know. This issue and my uncapacity to record the second audio in dual broadcastings are the only two things that are driving me crazy for days. The rest of Media Portal works like a charm.

I would apprecaite very much some help Thank you.
