[mythtv-users] garbage signal at top of screen

[Stelios Valavanis]

i don' tthink it's macrovision or anything ike that. my 2 TVs, VCRs, and tivo 
all tune into it just fine. maybe i should try xawtv just to see. all the 
settings in the mythtv gui setup are set to NTSC. what about the transcoder 
options set in the mythfrontend setup? anything there that could mess things 
up? i kept it all at the default low-ish setting (480x480 i think w/mpeg-4).
