An interesting update:
Last night I was watching the recording of Eurovision (hey, it's fun!

) that I did the other weekend off SBS. About 40 minutes in, the dreaded playback-stop bug hit and the Wintal reverted to live TV, and of course I had to restart the program and search throgh it for the bit where I was shut out. Not surprisingly, the playback-stop bug cropped up every time I went past that moment in the program at anything less than 5x search speed, and I was back to live TV and had to start again. As always, many colourful words were thrown around
But here's the thing.
Last weekend, I made a VHS copy of this
exact same recording of Eurovision for a family member. The entire four hours of the recording
played right through without stopping. Yet last night, suddenly the dreaded bug crops up in this same recording.
The only thing that's changed on my Wintal since I made the VHS copy is, of course, that I've recorded, watched and deleted other programs while leaving the Eurovision file on the disc. The Eurovision file itself is in the exact same place on the HD that it was since recording, of course.
Conclusions we can reach from this?
1. This is now definitely NOT a hard disc issue.
2. This is now definitely NOT a broadcast glitch issue.
3. This is now definitely NOT an RF interference issue.
4. It is likely being caused by corruption of the Wintal's record list as new recordings are added and/or deleted.
This all points to one thing.
FIRMWARE.I'll try and get in touch with Digenius and bring this thread to their attention. They might be able to shed some light on things. I've given up on Wintal.
