The new-look BBC iPlayer has not gone down well with some users judging by the thousands of posts to the catch-up service's message boards, with a huge number of those extremely negative with accusations that licence fee payers' concerns are being ignored.

Irate web users claim the new iPlayer, which officially launched earlier this month but has been running alongside the old version in beta since June, is riddled with bugs that are causing problems, particularly with those who download programmes on the service.

Typical titles of thread posts include "The new iPlayer has nearly had me in tears" and "Is anyone at the BBC listening to us?".

In a post put up yesterday, called "The new iPlayer revolt – the next step", one user called Osta claims to have trawled the message boards over a one-week period and found that the BBC is not responding to complaints.

"I can only assume that the BBC bigwigs are keen not to explore the shortcomings of their organisation too deeply, otherwise by now they would have acted upon the mounting weight of postings from BBC viewers and listeners about this subject," said Osta.

"This therefore leads me to think that it is a waste of time to keep posting messages on this website and instead those of us who are concerned about this matter should use the official complaints system that the BBC has available as well as other options outside of the BBC."

Osta claims there is almost "universal dislike and loathing of the new version".

The BBC downplayed the issue, pointing out that all launches have teething difficulties and that it is clearly stated that the message boards are not the appropriate channel for complaints.

"New products often have technical issues, so it's not a surprise to see a handful of comments about these appear on the message board after the launch," said a spokeswoman for the BBC.

"The BBC iPlayer Desktop still has a few minor problems that we're working through and we thank the people who have flagged this. We make very clear that this is a message board for BBC iPlayer users and not a customer services or complaints website, but that doesn't mean we're not listening, and problems are escalated to the product team. Outside these specific technical problems, the reaction to the new site has been very positive."
