[mythtv-users] Problem recording some programs

[shacky]

I am testing a MythTV box with one Hauppauge WinTV Nova-T 500 dual DVB-T card.
For a total of 15 recorded programs , 4 programs was not recorded
correctly, without any intervention by me.
These 4 programs are listed in Mythweb, but they does not have the
preview image and the .mpg file.
Other 11 programs are recorded correctly and I can see them.

These are the lines correlate to the time period of time of a fault
recorded (the title is Diritto di difesa "Stagione 1 Episodio 3" from
01:30 to 02:35. As you can see, no error is displayed.
