yes, of course, here the hdparm:

/dev/hda:
 multcount    = 16 (on)
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    =  8 (on)
 geometry     = 3333/255/63, sectors = 53550304, start = 0

and I forgot to say that if I stop to record the video and audio 
problem continue until I switch channel. If I watch a channel and 
record another one there is no problem, all works perfectly.
