I've been running 0.18 since it was released on DVB-T in the UK with a (version 909) Nova-T. It's quite normal for the adverts and the actual programme to be in different aspect ratios, at most I see the odd green frame / short garbled video but very rarely. You don't say what version of Myth you're running. The current SVN head is undergoing a major DVB re-write so i'd use the 0.18-fixes branch for a production system until that all settles down. Have a look in the logs to see if there's anything useful, otherwise try and get a backtrace (see the user guide for instructions). Steve
