I have a subscription for TV5monde ($10 a month) and unfortunately the image quality is very poor.
TV5monde says that they send TWC a HD feed.
Is there a possibility to have a better quality?
It depends on your market. Have you checked the channel lineup for your zip code on the TWC site to see if it is even offered in HD where you are? Some markets only offer SD.
@christophe Are you having quality issues with other stations? Have you always
had poor picture quality or is this a new issue?
