Thanks IM bhai....i knew it that it is box problem...what abt discovery HD?For me no such issues on Sony Six HD.
Can't check Travel XP as its not available on Tata Sky.
But from the screenshot its clear that it's not Broadcaster issue. If it's happening on selected channel only then its the box issue.
No bro. there is no fault in TV...as other channels come perfect...and also in my old 2011 box it was not an issueI think its a fault of TV.
