Spent 2 hours on the ZXvid module this afternoon. A fiddly process and I pondered many times on the £15 saving on having this fitted. Ah well, wouldn't be half the fun.
At this point there was no going back.
Finally ZXvid installed and ready for testing.
But, big but, no RF lead. Almost certainly discarded it along with the old 5in TV. Looks like testing will have to wait until next time...
