Hi Leroy!
Thank you very much for these tips! I had not seen those tips in my many
tips programs I have...
BTW, the LED does NOT blink..... It may blink a time or two on intinal turn
on but when the picture comes on the led goes out!
I will check these caps and the S-video soon and post back to you.
Thanks!
