Though if the programmes are only made in SD, there's only so much you can do even with high bitrates, you can't magic HD out of nothing. People are used to HD remasters of old shows, but there's still plenty that can't due to either being shot on video or the original film no longer existing (as well as lacking the will/money to do the job even when it does). Though you can help by not messing things up by not reducing the quality further with cropping and de-interlacing, both of which happen far too often these days (the clips in that video are pillarboxed, so there won't be the former at the very least, hopefully there won't be the latter either- which will place it above UKTV in technical quality!).
