[mythtv-users] RF Modulation

[Stuart Hodges]

HI,

	My VCR is not that capable. 

	However I did find a RF Modulator at RadioShack that had selectable channel 
output. So I thought I could just set this to an unused channel and combine 
the two cables (cable tv in and the modulator output). I get loads of static 
on the output from the modulator when I try this.

	I checked with no cable signal combined and everything is fine, no static. I 
tried a cable amp I had and this improved the situation, but its still 
unwatchable. 

	Any ideas ?

	I thought I could switch off the output using "ivtvfbctl /dev/fb1 -off" and 
use the normal modulator, but it seems to have no effect.

	Thanks,

		Stuart
